Effects of a common linguistic misrepresentation on judgments about the relationship between height and weight.

Researchers have debated whether laypeople can detect covariation and have tried to identify conditions that might facilitate or retard this ability. Language, especially linguistic representation of variables, seems important to consider since misrepresentation appears to be relatively common in linguistic exchanges. In the present theory-based experiment, 16 subjects were asked to make judgments about the relationship between height and either weight (heavy or light) or bodyfat (fat or thin). Data provided evidence of a powerful illusory association, that is, if tall, then thin; if short, then fat, and there was no compelling evidence to suggest that subjects understood the relationship between height and weight.

Self-reference effect in perceptual judgments by individuals and groups.

The existence of a "self-reference" effect in perception, such as that found in memory, was tested in groups and individuals. Subjects who judged a self-relevant stimulus were more accurate than those who judged a stimulus which was not self-relevant. No differences were found in the perceptual accuracy of groups versus individuals, and the self-reference effect was not more pronounced in groups or individuals. The effect may be explained in terms of the greater epistemic curiosity aroused by a self-referent stimulus and by the activation of hypothesized central nodes in the neural networks which produce perceptual judgments.

Magnitude estimation scaling judgments of speech intelligibility and speech acceptability.

20 female students in speech-language pathology provided magnitude estimation scaling responses for the speech intelligibility and acceptability of audio-taped speech samples varying systematically the number of consonant sounds produced correctly. Analysis indicated no significant over-all differences between listeners' judgments of intelligibility and acceptability; however, listeners tended to judge samples with fewer than 50% of the consonants correct as more acceptable than intelligible, and they judged samples with more than 50% consonants correct as less acceptable than intelligible.

Judgments of grammaticality of sentences with a differing number of arguments: a comparison of English and Japanese speakers.

This study explored native speakers' linguistic intuition as revealed in judging the grammaticality of sentences. Speakers of English (n = 36) and Japanese (n = 57) judged the relative grammaticality of sentences involving a verb which occurred together with one, two or three arguments. Findings showed that English speakers were more affected by the number of arguments in sentences. They judged sentences having three arguments as grammatical most often and ones having one or two arguments as grammatical less often. However, Japanese speakers gave rather similar and more grammatical judgments regardless of the number of arguments in sentences. The findings indicate a difference in tightness of argument structure in the two languages even when the sentences judged are simple sentences and they are given without any sentential context.

Judgment and decision-making: experts' and novices' evaluation of chess positions.

The present study examined how experts differ from nonexperts in estimation and evaluation during a judgment-and-decision task. In the experiment, the performance of 125 chess players (21 women and 104 men) whose mean age was 32.5 yr. (SD = 13.3) was examined to assess decision processes with an emphasis on postdecision differentiation and consolidation. Chess players of differing skill made evaluations of a complex middle-game chess position. The experimental condition was made by the means of chess articles with enclosed information, either about the current chess position or about other similar positions. Both novices and experts upgraded their chosen alternative in a postdecision phase more than intermediate level chess players did. Various explanations of these results are discussed.

Improving accuracy of veracity judgment through cue training.

The ability to make judgments of veracity was investigated to see if training individuals on visual, vocal, or verbal content cues of deception would increase their ability to judge whether a message was truthful. The overall rate of accuracy of judging veracity was significantly greater for subjects trained on verbal content cues. More specifically, for detecting truthful messages, subjects trained on verbal content cues had significantly greater accuracy than subjects who received no cue training, whereas for detecting deceptive messages, there were no significant differences in accuracy among conditions.

Evaluation of whole-body vibration by the category judgment method.

The purpose of this research is to establish a scale for comfort with regard to whole-body vibration by the category judgment method. Experiments were conducted with random signals as stimuli. These stimuli consisted of three types of signal, namely stimulus F, with flat PSD (Power Spectrum Density) ranging from 1 to 100 Hz, stimulus H with PSD, which became 20 dB higher at 100 Hz than at 1 Hz, and stimulus L that had a PSD 20 dB lower at 100 Hz. These signals were modified by Wk frequency weighting in accordance with ISO 2631-1, and the R.M.S. values were adjusted to be equal. In addition, the signal levels were varied over a range of five steps to create 15 kinds of individual stimuli. The subjects sat on a flat, horizontal metal plate mounted directly on the vibrator and were exposed to vertical vibrations before being asked to choose a numerical category to best indicate their perceived level of comfort (or otherwise) during each stimulus. The creation of this assessment scale, including the aforementioned categories, enabled not only clarification of the relationship between the vibration stimuli and the degree of comfort but also discovery of the connection between the frequency-weighted R.M.S. acceleration and the corresponding categories representing each degree of comfort without overlap. Moreover, it became clear that the subjects' assessment of the degree of comfort perceived differed with differences in the vibration spectrum.

Children's, adolescents', and young adults' reward allocations to hypothetical siblings and fairness judgments: effects of actor gender, character type, and allocation pattern.

The authors studied the reward allocation patterns, reasoning, and fairness judgments of 112 participants at 4 grade levels: kindergarten, 3rd grade, 9th grade, and college. Three story characters (an oldest, the most productive, and the physically disadvantaged) were depicted as siblings of the same gender, either sisters or brothers, who poured lemonade at a school picnic. Kindergartners' pattern of reward allocations indicated the use of an equality and productivity-based equity rule, whereas most of the older participants integrated considerations of both productivity and physical disadvantage in their allocations. Reasoning data were generally consistent with the allocation patterns. Reward allocations differed significantly by the gender of the characters, and fairness ratings differed significantly by the gender of the characters and the gender of the participant. Conclusions discuss the increasing coordination and consideration of more than one claim to the reward with development.

Judgments of learning: evidence for a two-stage process.

Three experiments tested the hypothesis that people make judgments of learning (JOLs) by attempting to retrieve the target first. If this were the whole story, then the reaction time (RT) functions for making JOLs with no special instructions would parallel those found when people are told to first attempt retrieval and then make a JOL. In the present data, monotonic functions, showing an increase in RT with decreasing JOL, were found when people were instructed to retrieve covertly or overtly and then make a JOL, as would be expected if retrieval fluency entirely determined JOLs. However, the functions for making uninstructed JOLs were different: Low JOLs were made quickly, not slowly, and the curves were inverted U shapes, rather than linear. Furthermore, people's memory performance was somewhat better, especially on low-JOL items, when they were instructed to first retrieve as opposed to when they were told only to make JOLs. To account for these data, we propose a two-stage model of JOLs, with the first stage occurring prior to attempted retrieval.

Time judgments in global temporal contexts.

With three experiments, we examined the effects of global temporal context on time judgments as gauged by constant errors (CEs) and estimates of a preferred period (P). In Experiment 1, participants in seven different conditions listened to sequences of a given rate (with interonset intervals ranging from 200 to 800 msec) and judged the relative duration of a final (comparison) time interval. No P emerged. In Experiments 2 and 3, we embedded the same rates in different global (session) contexts that varied according to (1) mean session rate, (2) standard deviation, (3) range, and (4) number of different rates in a session. Evidence from CEs indicated that P varied primarily as a function of mean session rate and range of tempi. The best predictor of errors involved a measure termed relative range (RR = range/mean session rate). A general algorithm incorporating RR successfully predicts P, and the implications of this algorithm are discussed.

Effects of instruction presentation mode in comparative judgments.

In each of two experiments, the comparative instructions in a symbolic comparison task were either varied randomly from trial to trial (mixed blocks) or left constant (pure blocks) within blocks of trials. In the first experiment, every stimulus was compared with every other stimulus. The symbolic distance effect (DE) was enhanced, and the semantic congruity effect (SCE) was significantly larger, when the instructions were randomized than when they were blocked. In a second experiment, each stimulus was paired with only one other stimulus. The SCE was again larger when instructions were randomized than when they were blocked. The enhanced SCE and DE with randomized instructions follow naturally from evidence accrual views of comparative judgments.

Recursive reminding: effects of repetition, printed frequency, connectivity, and set size on recognition and judgments of frequency.

In the present experiments, predictions of common path and recursive-reminding models of recognition (RG) and judgments of frequency (JOFs) were contrasted. The results indicated that each task is affected by study frequency, printed frequency, and associative connectivity. However, effect size analyses indicated that study frequency and item attributes show a double dissociation over tasks. Study frequency has a greater effect on JOFs than on RG, whereas printed frequency and associative connectivity have greater effects on RG than on JOFs. The recursive-reminding model predicts differential effects of study frequency, because it assumes that although both tasks are influenced by familiarity, JOF is more likely to be affected by recollective reminding as a procedure for encoding event frequency. Associative set size effects were absent in each task, suggesting that competitors play no role in either task.

Priming effects on temporal order judgments about words: perceived temporal priority or response bias?

In a temporal order judgment task, in which observers select which of two words appeared first, Stolz (1999) found that observers were more likely to select the word that had been semantically primed. Using repetition priming, we replicated Stolz's finding and extended her results by demonstrating that the effect was due to both (1) repetition priming causing the primed item to be perceived as having occurred earlier and (2) a response bias to guess the repetition primed item as the correct response. We discuss our new finding that priming induces an attentional precedence effect in the context of previous research suggesting that exogenous spatial cuing induces an attentional precedence effect but identity or semantic priming may not.

Effects of wording and stimulus format on the use of contingency information in causal judgment.

There are four kinds of contingency information: occurrences and nonoccurrences of an effect in the presence and in the absence of a cause. Previous studies have shown that these four kinds are not given equal weight in causal judgment. The present research was designed to test two hypotheses about this unequal weighting: that weightings are influenced by the form of the question and other features of the stimulus materials and that unequal weightings occur, in part, because individual differences in the use of contingency information are not evenly distributed across the four kinds of information. Support was found for both hypotheses. However, the effects of question wording were not always as had been predicted, indicating that more needs to be learned about how people interpret the task, instructions, and materials they are given.

The effect of motion on tactile and visual temporal order judgments.

Four experiments were conducted, three with tactile stimuli and one with visual stimuli, in which subjects made temporal order judgments (TOJs). The tactile stimuli were patterns that moved laterally across the fingerpads. The subject's task was to judge which finger received the pattern first. Even though the movement was irrelevant to the task, the subjects' TOJs were greatly affected by the direction of movement of the patterns. Accuracy in judging temporal order was enhanced when the patterns moved in a direction that was consistent with the temporal order of presentation--for example, when the movement on each fingerpad was from right to left and the temporally leading site of stimulation was to the right of the temporally trailing site of stimulation. When movement was inconsistent with the temporal order of presentation, accuracy was considerably reduced, often well below chance. The bias in TOJs was unaffected by training or by presenting the stimuli to fingers on opposite hands. In a fourth experiment, subjects judged the temporal order of visual stimuli that, like the tactile stimuli, moved in a direction that was either consistent or inconsistent with the TOJ. The results were similar to those obtained with tactile stimuli. It is suggested that the bias may be affected by attentional mechanisms and by apparent motion generated between the two sites on the skin.

The influence of category membership of stimuli on sequential effects in magnitude judgment.

The present study addresses the problem of whether range effects and sequential dependencies are affected by stimulus category membership in the same way. Two sets of squares differing in color were presented to subjects. The subjects were asked to judge them according to size, under two instructions. The separation instruction required them to judge each square solely in relation to its own category. The integration instruction required them to ignore category membership. The results indicated that, under the separation instruction, the range effects, as well as the sequence effects, confined themselves to stimuli of the same category. Under the integration instruction, however, the squares were judged in relation to the range of all the stimuli, and sequential effects were independent of the stimulus category. This parallel trend in the category-specific effects of range and preceding stimuli was found for judgments, as well as for reaction times. The findings are discussed with regard to models of sequential effects.

The revelation effect in frequency judgment.

In three experiments, we explored the revelation effect in a frequency judgment task. Participants estimated the frequency of words that had been presented one, two, four, or eight times. At test, half the words were revealed by completing word fragments, and half were presented intact. Estimated frequencies were reliably higher for revealed than for intact words, and in two of the three experiments, the revelation effect became larger as actual frequency increased. A revelation effect was obtained whether the revealed word was the same as (Experiment 1) or different from (Experiment 2) the word judged for frequency. Frequency estimates were higher for more distorted test items (Experiment 3).

Fluency of retrieval at study affects judgments of learning (JOLs): an analytic or nonanalytic basis for JOLs?

The fluency of retrieval during a test of memory has been implicated as a cue for judgments of learning (JOLs), but little is known about how fluency affects JOLs. In three experiments, we investigated (1) whether the fluency of generation during study may be a cue for JOLs and (2) whether such fluency effects are mediated by an analytic or nonanalytic inference. To accomplish our goals, we used a learner-observer-judge method. While studying paired associates, learners generated some targets at study. For these items, their JOLs were negatively correlated with the time taken to generate targets. Observers watched learners generate targets and then predicted learners' memory performance. Judges also made JOLs but did not watch the learners generate targets. JOLs from all groups were negatively related to learners' latencies to generate targets, with the magnitude of the relationship equivalent for learners and observers and lower for judges. These and other findings are consistent with the conclusions that the fluency of generation at study is a cue for JOLs and that such fluency effects are partly mediated by an analytic inference about how fluency is related to memory.
