Cognitive processes mediating behavioral change.

The present experiment was designed to test the theory that psychological procedures achieve changes in behavior by altering the level and strength of self-efficacy. In this formulation, perceived self-efficacy. In this formulation, perceived self-efficacy influences level of performance by enhancing intensity and persistence of effort. Adult phobics were administered treatments based upon either performance mastery experiences, vicarious experiences., or they received no treatment. Their efficacy expectations and approach behavior toward threats differing on a similarity dimension were measured before and after treatment. In accord with our prediction, the mastery-based treatment produced higher, stronger, and more generalized expectations of personal efficacy than did the treatment relying solely upon vicarious experiences. Results of a microanalysis further confirm the hypothesized relationship between self-efficacy and behavioral change. Self-efficacy was a uniformly accurate predictor of performance on tasks of varying difficulty with different threats regardless of whether the changes in self-efficacy were produced through enactive mastery or by vicarious experience alone.

The Assessment of Basic Learning Abilities (ABLA) test predicts the relative efficacy of task preferences for persons with developmental disabilities.

BACKGROUND: Prior studies have showed that presentation methods could affect the accuracy of a choice assessment. METHODS: In the current study, high- and low-preferred work tasks were identified in nine adults with developmental disabilities. Both tasks were then introduced in pairs within a choice assessment using the actual tasks, pictures of the tasks and spoken descriptions of the tasks. Participants were also given the Assessment of Basic Learning Abilities (ABLA) test that evaluated their discrimination skills. RESULTS: For five of the participants, their consistent choice of preferred task was predicted by their discrimination skills as assessed by the ABLA. CONCLUSIONS: These findings extend that of Conyers et al. whereby the systematic assessment of discrimination skills could predict the effectiveness of different presentation methods in this population.

Complex, multimodal behavioral profile of the Homer1 knockout mouse.

Proteins of the Homer1 immediate early gene family have been associated with synaptogenesis and synaptic plasticity suggesting broad behavioral consequences of loss of function. This study examined the behavior of male Homer1 knockout (KO) mice compared with wild-type (WT) and heterozygous mice using a battery of 10 behavioral tests probing sensory, motor, social, emotional and learning/memory functions. KO mice showed mild somatic growth retardation, poor motor coordination, enhanced sensory reactivity and learning deficits. Heterozygous mice showed increased aggression in social interactions with conspecifics. The distribution of mGluR5 and N-methyl-D-aspartate receptors (NMDA) receptors appeared to be unaltered in the hippocampus (HIP) of Homer1 KO mice. The results indicate an extensive range of disrupted behaviors that should contribute to the understanding of the Homer1 gene in brain development and behavior.

Gender roles as developmental pathways.

Male and female gender roles are discussed as developmental pathways in terms of four related descriptive dimensions: the first three, rigidity, complexity and consistency, are all concerned with processes operating at particular stages of development; the fourth, continuity, is concerned with the overall developmental pathway. The limited evidence available indicates the following: there is a more rigid male role in childhood, but the evidence for adults is less clear; there is some evidence of greater complexity and inconsistency in the male role during childhood; developmentally, the female role becomes less flexible at adolescence whereas the male role becomes more flexible and varied; the female role shows more change across the adult life-span, particularly at the birth of the first child. The wider societal and historical implications of these conclusions, and their relation to role-related difficulties, are discussed.

Assessing the anxious patient.

Dental anxiety is a problem for many adults and children and for many patients anxiety acts as a barrier to treatment: avoidance of treatment, irregular attendance or attendance for emergency treatment only being typical ways of dealing with the problem. For the dental team a patient's anxiety poses major management problems, as an anxious patient may require more time for treatment, is very likely to miss appointments and may have raised pain thresholds. A major cause of stress for clinicians is the management of anxiety in their patients.

The assessment of peer selection and peer environmental influences on behavior using pairs of siblings or twins.

Many studies have found strong peer correlations for a variety of problem behaviors that begin in adolescence (e.g. substance use). Such correlations are commonly attributed to peer influences, but could also be explained by selective ('assortative') friendship: the tendency for those with similar patterns of behavior to become friends. Here we show how, under certain assumptions, cross-sectional data from pairs of siblings or twins and their peers may be used to resolve the contributions of peer selection and reciprocal peer environmental influences to peer resemblance. We performed power calculations to determine necessary sample sizes for rejecting with 80% power, at the 5% significance level, the hypothesis of only peer selection effects, or only reciprocal peer environmental effects. A false hypothesis of only selective friendship effects was always easier to reject than a false hypothesis of only reciprocal peer environmental influences. Limitations of these simulations, including uncertainty about the most appropriate way to model peer selection, are discussed.

From mimesis to agency: clinical steps in the work of psychic two-ness.

In this paper, through the study of the clinical process of a girl starting treatment at the age of 3 years 10 months, who was thought of as a 'dummy' by her family and who came for consultation when the assumed genetic aetiology was questioned, the authors build upon Tustin's contributions on the context of togetherness and the crisis of two-ness, and upon Eugenio and Renata Gaddini's on the precursor object. The mimetic phenomena enacted with an older brother and at the kindergarten are found to result from cumulative trauma at her contacting a loving but mind-blind mother. After an initial stage of transference autism, enactment in the session of the traumatic situation was the ?rst step in surmounting her autistic pseudo-stupidity. Mimetic transference dynamics took place principally at the level of the gaze, leading to the unfolding of the work of two-ness to a differentiation from the analyst as psychic breast, on the road to symbol formation and personal agency.

The effects of modelling on the contingent praise of mental retardation counsellors.

A multiple-baseline design was used to evaluate the effects of a simple modelling procedure on the contingent praise of five counsellors while they conducted hygiene-training sessions in toothbrushing and hand-and-face washing with severely retarded children. After varying numbers of baseline sessions, each counsellor watched a model who conducted a series of toothbrushing sessions, in which he conspicuously praised correct toothbrushing responses and approximations to correct responses. No modelling occurred during hand-and-face washing sessions. As a result of several exposures to the model's performance, levels of response-contingent praise provided by four of the five counsellors during toothbrushing sessions increased sharply over baseline. The levels of counsellor praise showed parallel increases during hand-and-face washing sessions. A two-week followup showed that the levels of praise obtained through modelling were maintained in the model's absence.

Modifying delinquent behavior: beginnings and current practices.

The beginnings of behavior therapy with delinquents are traced to the early 1960's when a number of case studies and demonstration projects were first presented. Current practices are reviewed in more detail. In institutions for delinquents, many token economies have gradually developed; their shortcomings and results are discussed. In clinic settings, several individual and group techniques are reviewed as they are currently practiced. A major trend is seen as being away from institutional and traditional clinic behavior therapy. Direct community intervention is seen as the most parsimonious mode for modifying and preventing delinquent behavior, and several model programs are described.

Modifying maternal teaching style: effects of task arrangement on the match-to-sample performance of retarded preschool-age-children.

Twenty-one mothers and their retarded preschool-age children were observed during six teaching sessions. Following the first three sessions, each mother-child dyad was assigned to one of the three groups. Groups were matched on measures of mother and child behavior and on measures of various mother and child background factors. Prior to the last three teaching sessions, mothers received instructions to modify certain aspects of their teaching style. The results indicated that children of mothers who had been instructed to present the materials of the task systematically obtained significantly higher performance scores during training than did children of mothers who either received no instruction or had been told to increase positive feedback for correct responses. Further, 6 of 7 children whose mothers had altered the manner in which they presented the task materials showed improvement on a test administered after training. These results suggest that nonverbal activities which precede responding are critical aspects of teaching style and deserve more attention than they have received in the past.

Infants' behavioral reenactment of "failed attempts": exploring the roles of emulation learning, stimulus enhancement, and understanding of intentions.

Two studies were conducted to examine whether infants' reenactment of intended but unconsummated acts in A. N. Meltzoff's (1995) failed-attempt paradigm is due to reading the adult's underlying intention or to the effects of nonimitative social learning processes. Two novel conditions that emphasized the object affordances and the spatial contiguity of the object sets were devised. When infants' first actions only were counted, infants who observed the full-demonstration model produced more target acts. When all target acts produced within the 20-s response period were counted, infants in the emulation-learning and spatial contiguity conditions produced as many target acts as infants in the full-demonstration and failed-attempt conditions. This pattern of findings suggests that nonimitative social learning processes may influence infants' response in the behavioral reenactment paradigm.

The forest, the trees, and the chameleon: context dependence and mimicry.

Three studies examined the relation between context dependence in information processing and behavioral mimicry. In Experiment 1, a field-dependent cognitive style was related to a greater tendency to mimic a target's behavior. In Experiment 2 context dependence was experimentally manipulated, and results showed more mimicry in the session where a context-dependent processing style was induced compared with the session where a context-independent processing style was induced. Experiment 3 provided evidence for bidirectionality in the relation between context dependence and mimicry. Specifically, participants whose posture and behavior had been unobtrusively mimicked by an experimenter subsequently processed information in a more context-dependent manner than did nonmimicked participants. Taken together, these results illustrate the interplay between basic cognitive and behavioral processes.

Social referencing by young chimpanzees (Pan troglodytes).

Social referencing is the seeking of information from another individual and the use of that information to evaluate a situation. It is a well-documented ability in human infants but has not been studied experimentally in nonhuman primates. Seventeen young nursery-reared chimpanzees (14 to 41 months old) were observed in a standard social referencing paradigm in which they received happy and fear messages concerning novel objects from a familiar human caregiver. Each chimpanzee looked referentially at their caregiver, and the emotional messages that they received differentially influenced their gaze behavior and avoidance of the novel objects. It is concluded that chimpanzees can acquire information about their complex social and physical environments through social referencing and can use emotional information to alter their own behavior.
