Memories of uncertain origin: dreamt or real?

The existence of a memory whose origin, real or dreamt, was uncertain was reported by just over half of an undergraduate sample of 358. Each respondent described one such memory if they had one. The memories were typically of mundane events, although 10 respondents described possible crimes. Respondents were often concerned to resolve the origin of these memories. Their plausibility, vividness, and how well the events fitted into one's life were often considered by the respondents, but where resolution occurred it was frequently based on evidence obtained from the physical or social environment. The reported qualities of the event did not correlate with whether the respondent thought it more likely to have been originally a dream or a real event.

Sonography and MRI of rectus abdominis muscle strain in elite tennis players.

OBJECTIVE: The objective of this study was to describe the imaging findings at sonography and MRI of rectus abdominis muscle strain in tennis players. CONCLUSION: Asymmetrical hypertrophy of the recti is seen in elite tennis players. The muscle belly hypertrophies on the side opposite the dominant arm and is subject to muscle tears of its deep fibers below the umbilicus. Imaging can be used to show these injuries.

Simple optimisation.

Sometimes, an organism can use a simple optimisation heuristic. It does not need to calculate optimality functions, but can instead proceed by evaluating gradients in its environment and following a path that leads towards a local maximum or minimum.

Memory for true and false autobiographical event descriptions.

This study examined how participants respond to different types of false autobiographical event descriptions. Three attributes of autobiographical events (participant, location, and activity) were systematically altered to create different forms of false event description and these were examined, along with true events, to see if participants were more or less likely to rate the experience as remembered. The event attributes manipulated within false events systematically influenced the participant's memory ratings, and completely false events were the least likely to be identified as false. Mechanisms associated with access to autobiographical memory knowledge bases by which event attributes might cue an event as true or false are discussed.

Themes, events, and episodes in autobiographical memory.

The process by which experience is divided into events was examined. Experiment 1 involved diarists recording their experiences over a 3-month period. Diary entries were later transcribed onto cards and the diarists arranged their cards so as to define events they had experienced, and in a separate phase arranged their cards so as to describe the themes that reflected their life. Examination of event- and theme-building strategies indicated that boundaries were frequently used, and events and themes were often formed from clusters of experience combined using content association rather than temporal sequence. Experiment 2 involved photographs taken by the participants, employed the same procedures as in Experiment 1, and revealed event- and theme-building strategies similar to those identified in Experiment 1. In Experiment 3 the size of the stimulus set from which events and themes were constructed was manipulated; this did not influence construction strategies. Overall, the experiments show that both autobiographical events and themes frequently consist of episodes taken from more than 1 day.
