STIVID: A VBSCRIPT-based program for adding visual and auditory stimuli on videotapes

Some psychological experiments require placement of visual and auditory stimuli on predefined frames in a videotape. We introduce STIVID (STImuli on VIDeo) as a method of performing this task. STIVID can add images, words, simple shapes, and audio tones to specific frames of existing video files created in AVI format. STIVID is written in Visual Basic and uses VBScripts to modify the AVI files. Three applications of this program are discussed: adding stimuli for reaction time experiments with couples watching a relational conflict, use of distractors in ADHD experiments, and placing eye masks on actors in existing videotapes to manipulate perceptibility of the target’s facial expression during the mind-reading process.     

The Implications of Conjunctive and Disjunctive Forgiveness for Sexual Abuse

This article examines the relationship between forgiveness styles (conjunctive and disjunctive models) and sexual abuse. Surveys from 114 university students were analyzed for differences between non-sexually abused and sexually abused subjects on a number of psychological and physical well-being variables. A number of differences were found including higher levels of reported verbal and physical abuse for the sexually abused subjects. Only one sexually abused subject was found that fit the pattern of conjunctive forgiveness (one of reconciliation) towards the offender. The majority of sexually abused subjects preferred to keep their distance from the abuser, regardless of the extent to which the abuser had been forgiven. The results suggest that reconciliation within forgiveness may not be an appropriate goal for all subjects.     

Psychometric testing and applications of the Body Attitudes Questionnaire translated into Portuguese

Although many body attitudes scales have been developed, none have been translated into Portuguese. This study aimed to translate the Ben-Tovim and Walker Body Attitudes Questionnaire and assess validity and reliability for a Brazilian sample. Women with (n = 39) and without (n = 57) eating disorders completed the scale, to assess discriminant validity. Convergent validity was assessed by the correlations between the scores and a measure of body dissatisfaction. The questionnaire was applied twice to controls after 1 mo. to evaluate reliability. Eating-disordered women had significantly higher mean scores on Feeling Fat, Disparagement, Salience and Lower Body Fatness, and lower scores on Attractiveness. No mean difference on Strength and Fitness was found. Most subscales were significantly correlated with the body-dissatisfaction measure. Test-retest coefficients ranged from .57 to .85. The translated version of the Body Attitudes Questionnaire seems to be a valid and reliable measure of body attitudes.     

"Economic man" in cross-cultural perspective: behavioral experiments in 15 small-scale societies

Researchers from across the social sciences have found consistent deviations from the predictions of the canonical model of self-interest in hundreds of experiments from around the world. This research, however, cannot determine whether the uniformity results from universal patterns of human behavior or from the limited cultural variation available among the university students used in virtually all prior experimental work. To address this, we undertook a cross-cultural study of behavior in ultimatum, public goods, and dictator games in a range of small-scale societies exhibiting a wide variety of economic and cultural conditions. We found, first, that the canonical model - based on self-interest - fails in all of the societies studied. Second, our data reveal substantially more behavioral variability across social groups than has been found in previous research. Third, group-level differences in economic organization and the structure of social interactions explain a substantial portion of the behavioral variation across societies: the higher the degree of market integration and the higher the payoffs to cooperation in everyday life, the greater the level of prosociality expressed in experimental games. Fourth, the available individual-level economic and demographic variables do not consistently explain game behavior, either within or across groups. Fifth, in many cases experimental play appears to reflect the common interactional patterns of everyday life.     

Processes of task-set reconfiguration: switching operations and implementation operations

When participants are asked to shift between four dimensionally organized tasks which differ in the type of judgment (numerical vs. spatial) and/or the judgment-to-response mapping (compatible vs. incompatible), a characteristic profile of shift costs can be observed. It can be accounted for in terms of two different types of operations: generalizing switching operations on a dimensionally organized set of task representations and implementation operations [T. Kleinsorge, H. Heuer, Psycholog. Res. 62 (1999) 300]. In a first experiment we corroborated our previous findings by way of a new procedure that makes it possible to estimate shift costs unconfounded by a number of factors that are likely to affect estimates of shift costs based on more conventional procedures. In a second experiment we investigated the endogenous and exogenous nature of the postulated types of operations. The characteristic profile of shift costs disappeared when long precue intervals (PCIs) were used. Augmented by a formal analysis, this finding suggests that both switching and implementation operations are endogenously controlled. In addition, there remained some residual shift costs which were essentially insensitive to the nature of the task shift but depended on the difficulty of the new task. Most likely they reflect a process of consolidation of an already configured task set.     

Stimulation seeking and hyperactive behavior in children with ADHD: a re-analysis

To examine the stimulation-seeking function of hyperactivity in children with ADHD, Antrop and colleagues analyzed the behavior of 30 hyperactive and 30 nonhyperactive children during a waiting situation, either with or without extra stimulation. The behavior was assessed by frequency measures. In their study it was hypothesized that children with ADHD would show a greater decrease in activity in the presence of stimulation than control children. Since confirmation for this hypothesis was only found for 2 of 25 target behaviors, the present re-analysis included other behavioral measures to assess two relationships: first, how hyperactivity varies under fixed time conditions, using measures of duration and intensity of behavior instead of frequency measures, and second, how the perceived duration of waiting time affects behavior. Analysis indicated that children with ADHD showed a greater decrease in behavior in the presence of stimulation for touching objects and movements of trunk, as reported. Further, children who underestimated the waiting period were more apt to seek additional stimulation in its absence than those who overestimated the waiting period.     

Determinants of diagnostic prototypicality judgments of the personality disorders

We evaluated the impact of three factors that have been suggested to be important determinants of the diagnostic process pertaining to personality disorders: (a) the number of features representative of a personality disorder category; (b) the extent to which those features are typical of the category, and (c) the dominance or proportion of category features to the total number of features. Thirty-two clinical psychologists evaluated 12 profiles of hypothetical patients in which these factors were varied factorially. The results revealed strong effects of typicality and dominance, but no effects for number. Implications for the assessment and classification of personality disorders are discussed.     

A room with a view and a polarizing cue: individual differences in the stimulus control of place navigation and passive latent learning in the water maze

We investigated individual differences in the stimulus control of navigational behavior in the water maze by comparing measures of place learning in one environment to measures of latent learning (via passive placement on the goal platform) in a novel environment. In the first experiment, 12 rats were trained to find a slightly submerged hidden platform at a fixed location in room A for 10 days (4 trials/day). Fast and slow place learners were identified by their mean escape latency and cumulative distance to the goal during acquisition. The same animals were then given a 2-min passive placement on the submerged platform in room B. Latent learning was assessed by the animal's escape latency on a single swim trial immediately following the placement in room B. The results showed that the good latent learners in room B were not necessarily the fast place learners in room A. This weak correlation may be related to the fact that some rats swam near the area in room B that corresponded to the former goal location in room A relative to a common polarizing cue (i.e., the door/entrance to both rooms). When the view of the door was blocked in a second experiment a significant positive correlation between place acquisition and the latent learning test was obtained, although escape performance following passive placement was not improved. These findings suggest that while place navigation and latent learning via passive placement may involve some common cognitive-spatial function, other associative (S-S and/or S-R) processes that occur during place navigation/active movement may be required for animals to exhibit truly accurate navigational behavior characteristic of asymptotic escape performance in the water maze. Additional implications for neurobiological studies using a procedural pretraining design are discussed.     

Comparing music- and food-evoked autobiographical memories in young and older adults: A diary study

Previous research has found that music brings back more vivid and emotional autobiographical memories than various other retrieval cues. However, such studies have often been low in ecological validity and constrained by relatively limited cue selection and predominantly young adult samples. Here, we compared music to food as cues for autobiographical memories in everyday life in young and older adults. In two separate four-day periods, 39 younger (ages 18–34) and 39 older (ages 60–77) adults recorded their music- and food-evoked autobiographical memories in paper diaries. Across both age groups, music triggered more frequent autobiographical memories, a greater proportion of involuntary memories, and memories rated as more personally important in comparison to food cues. Age differences impacted music- and food-evoked memories similarly, with older adults consistently recalling older and less specific memories, which they rated as more positive, vivid, and rehearsed. However, young and older adults did not differ in the number or involuntary nature of their recorded memories. This work represents an important step in understanding the phenomenology of naturally occurring music-evoked autobiographical memories across adulthood and provides new insights into how and why music may be a more effective trigger for personally valued memories than certain other everyday cues.
