Accounting for taste: Individual differences in preference for harmony

Although empirical research on aesthetics has had some success in explaining the average preferences of groups of observers, relatively little is known about individual differences in preference, and especially about how such differences might covary across different domains. In this study, we identified a new factor underlying aesthetic response—preference for harmonious stimuli—and examined how it varies over four domains (color, shape, spatial location, and music) across individuals with different levels of training in art and music. We found that individual preferences for harmony are strongly correlated across all four dimensions tested and decrease consistently with training in the relevant aesthetic domains. Confirmatory factor analysis revealed that cross-domain preference for harmony is well-represented as a single, unified factor, with effects separate from those of training and of common personality measures.     

Gender differences in anger and fear as a function of situational context

Gender differences in the reported intensity of anger and fear toward hypothetical males and females were explored in three age groups (6–12 year olds, 14–16 year olds, and adults over 30) located in two different geographic areas. The samples were primarily Caucasian and included a wide range of socioeconomic groups. Subjects reported on the intensity of feelings elicited by characters in an emotion story task in which three aspects of situational context were varied: the gender of the story characters eliciting the feeling (all situations), the stereotypic gender-typed or cross-gender behavior of the eliciting character (four situations), and the affective quality of the situations (four situations). Across all three age groups, situations that were frightening, anger-provoking, or that depicted stereotypic male-negative behavior elicited the most consistent subject gender and character gender differences in reported fear and anger. Relative to males, females of all ages reported more fear in frightening, anger-producing, and male-negative stereotypic situations. Males were reported to be more frightening and anger-producing than were females in those same situations. The data also suggested that with development, females reported less intense fear of females, while males reported less intense fear of males.This research was supported by a Gender Roles grant from the Rockefeller Foundation. We appreciate their support. We would also like to thank the public school systems of Milton, Norwood, and Watertown, Massachusetts, and Saskatoon, Saskatchewan, Canada. Finally, we would like to thank Lance Davidow, John Houlihan, and Theodore Cross for statistical consultation and/or computer programming, as well as all the parents, children, and adolescents who participated in the study.     

From Theory to Practice: Facing Ethical Challenges as a Clinical Intern

Although formal ethics classes provide a basic foundation in managing ethical dilemmas, professionals often point to their experiences on internship as an important training ground for consolidation of their ethical development. Clinical interns face many personal and professional transitions that can lead to a number of ethical dilemmas. Effective collaboration between administrative staff, supervisors, and interns can create a pragmatic model for negotiating these dilemmas. In this paper, issues related to balancing intern competency with training and patient/client needs, managing dual relationships with supervisory staff, and dealing with differences in orientation are addressed from the perspective of both the site and the intern. We also discuss ways in which problems can arise and how both sides can work together systematically to negotiate those problems. To illustrate this process, we discuss cases involving effective collaboration between interns and sites. Finally, the authors assert the need for formal, empirically supported training in classic ethical issues, but also in contemporary ethical issues arising from the ever-evolving field of mental health service delivery and unique challenges accompanying these advances.     

Mental rotation as a mediator for sex-related differences in visualization

This study was designed to analyze whether Mental Rotation (MR) played a role as a mediating variable for sex-related differences in Visualization (VZ). Two psychometric tests measuring MR and VZ were applied to a representative sample of 309 males and 390 females in their last year of high school. Three non-zero correlations between sex and MR, sex and VZ, and MR and VZ were found, and the effect of sex on VZ was eliminated when MR was introduced as a covariable. When three subgroups of different VZ ability were made by dividing up the VZ distribution by the first and third quartiles, sex-differences were only found for the high-scorers group, for which previous results were replicated. Results clearly indicate that MR is a plausible mediator variable for sex differences in VZ when such differences do exist. Theoretical, methodological and practical consequences of these results are discussed.     

Expertise differences in a video decision-making task: Speed influences on performance

Video clips of different speeds were used in a simulation of decision-making in Australian football to test the effects on decision accuracy and decision time. Elite and sub-elite and novice Australian footballers watched videos in six speeds (0.75, 1.0, 1.25, 1.5, 1.75 and 2.0 times normal speed). Participants responded by using a mouse-click to indicate where they would pass the ball for that particular video clip. The elite and sub-elite groups also rated each clip for how ‘game-like’ the decision-making felt. The elite group was significantly more accurate than the sub-elite and novice groups, and the sub-elite group was more accurate than the novice group. Within-speed analysis showed the elite group excelled at the faster video speeds. The use of speeded video delineated clear expertise differences between the groups at the 1.5 speed. Elite and sub-elite players identified the 1.25 and 1.5 speeds as most ‘game-like’ for decision-making. These results show that athletes perceive moderately speeded video as more game-like. Speeded video is further speculated to have allowed elite athletes to perform more automatically, with a faster processing efficacy, a key characteristic of elite performance. This study suggests the use of speeded video as a potential new research paradigm to explore expertise and a viable method for future training interventions for decision-making.     

Cultural differences in emotions: a context for interpreting emotional experiences

In this article, it is suggested that cross-cultural assessment of emotional disturbances would benefit from the consideration of cultural differences in the modal, and normative emotions. A summary of the research literature on cultural differences in emotions, in particular in antecedent events, subjective feeling, appraisal, and behavior is provided. Cultural differences in emotions are understood functionally, such that the most prevalent emotional phenomena in a culture are those that fit and reinforce the distinct cultural models (i.e. goals and practices) of self and relationship. It is argued that a culture-sensitive approach to emotional disturbances would entail the assessment of emotional phenomena that are dysfunctional to the cultural models of self and relationship.     

Language as context for the perception of emotion

In the blink of an eye, people can easily see emotion in another person's face. This fact leads many to assume that emotion perception is given and proceeds independently of conceptual processes such as language. In this paper we suggest otherwise and offer the hypothesis that language functions as a context in emotion perception. We review a variety of evidence consistent with the language-as-context view and then discuss how a linguistically relative approach to emotion perception allows for intriguing and generative questions about the extent to which language shapes the sensory processing involved in seeing emotion in another person's face.     

Exploring numerical proportions in a unique context: The group support systems meeting environment

This paper reports the results of a study examining issues of group gender composition in a meeting setting employing group support systems (GSS). Research examining the effects of numerical proportions on group behavior has traditionally been conducted in settings where use of technology by groups is minimal. This research, however, examines the impact of varying group gender composition on brainstorming, social interaction patterns, and attitudes when technology is employed to facilitate and structure group process. In this setting, we find no gender-related differences in computer-based brainstorming. In the accompanying oral discussions, however, males display a higher proportion of task-related answers than females and uniform groups express more maintenance behavior than groups consisting of mixed genders. Our findings also show that uniform gender groups perceive greater participation in the decision process than skewed groups. Despite these gender-related differences, we found relatively little support for Kanter's Numerical Proportions Model in a GSS setting, given the range of measures explored in this study.     

The anti-candidate considers starting a group

The hurdles to starting a group reside primarily in the therapist. The author shares how her unformulated dread in beginning a private practice psychotherapy group was enacted and then transformed by the group training process itself. The discussion illustrates how disavowed affects-and affects of disavowal-were contained for eventual understanding and growth within the curative embrace of the training group.     

Sex-related differences and visual-spatial mental imagery as factors affecting symbolic motor skill acquisition

The ability of males and females to use visual-spatial imagery as a facilitator of symbolic motor skill acquisition was investigated. Subjects, ordered by gender into control and mental imagery groups, performed 15 trials on a mirrored drawing task. The results indicated that, although both male and female mental imagery groups performed the task more skillfully than the control groups, the male mental imagery group scores over the early stages of performance were better as compared to the female mental imagery group scores. This difference was eradicated during the latter stages of performance. The findings, in addition to supporting the positive effects of mental imagery, lend support to the hypothesis that sex-related differences in selected visual-spatial tasks may be amendable through training followed by practice.     

Avengees' perspectives on revenge: Commitment as a predictor and relationship type differences

This study investigated how people respond emotionally to and make sense of the experience of being on the receiving end of an angry relationship partner's attempted revenge. Using an interdependence theory framework, we tested hypotheses concerning the role of commitment and investigated differences due to relationship type. We asked participants (N = 439) if they had experienced revenge at the hands of either a romantic partner, family member, or associate. Among those who had (N = 254), we found support for hypotheses linking commitment with avengees' affective and evaluative responses to being the target of revenge, but little evidence that these associations vary by relationship type. Possible routes by which commitment may influence people's experiences as avengees are discussed.     

The role of a mentoring group for family therapy trainees and therapists of color

This article discusses the development, process, and impact of a mentoring group for family therapists of color. A within-group process for trainees of color in a predominantly White institution can provide a valuable resource for support, validation, empowerment, and collective action. The article examines how such mentoring promotes the effectiveness of therapists of color, as well as the practices and goals of social justice and diversity within training institutions and the field in general. Reflections and recommendations for implementing such a group are offered, as well as a personal narrative of a group member's experience of finding her voice in the group.     

Computational modeling of individual differences in short term memory search

Modeling of individual or group differences, believed to be a powerful test for computational models, is still rare in current cognitive science. In this paper, we discuss alternative approaches to the computational modeling of both qualitative and quantitative differences among individuals as well as groups of individuals. Then, an example is presented of how accounting for individual differences in short term memory (STM) search can bring us insight into cognitive processes underlying this phenomenon, insight that otherways would be impossible. The two-phase computational model of memory search implements the idea of working memory (WM) focus of attention (FA): due to updating process a few items may be actively kept and easily accessed in ACT-R goal buffer. FA is being scanned serially first, and if the scan result is negative, a parallel chunk retrieval from active part of declarative memory outside the FA may run with certain probability. The model aptly simulates steep decrease in accuracy as well as steep increase in latency for responses to five most recent stimuli. The model also predicts the observed effect of faster negative responses than positive responses to less recent stimuli. Most important, with manipulation to only one of its parameters (i.e., the capacity of FA) our model is able to predict 94% of variance for two groups of participants that differed in latency patterns (i.e., ‘serial-like’ vs. ‘parallel-like’ groups) of the search process.     

Mastery goal orientation and cognitive ability effects on performance in learner‐guided training

To conserve resources, organizations are increasingly turning to learner‐guided training methods in which workers are given control over when, how, and what they cover in the learning process. However, the impact of individual differences such as goal orientation and cognitive ability has not been adequately addressed in learner‐guided training. This study seeks to advance our knowledge of how these differences affect performance through previously unexplored pathways. Specifically, we examined the indirect effects of mastery goal orientation and cognitive ability on post‐training performance in a learner‐directed training context. Findings indicate that off‐task thoughts mediate the positive effect of mastery goal orientation on post‐training performance, while declarative knowledge mediates the positive effect of cognitive ability on post‐training performance.     

Developmental differences in children's understanding of epistemic authority

An experiment was carried out to examine age differences in children's understanding of epistemic authority and its role in conversation. Two hundred and forty-six children from two age groups (6–7 and 11–12 years) were asked to make an independent judgement as to the equality or inequality of two lines in an optical illusion. Experimental conditions varied; ‘expertise’ in the task was given by training in a measurement algorithm and ‘familiarity with related stimuli’ by being shown illusions other than the test stimulus in training. Subjects who had answered independently that the lines were equal in length were paired with a same-age subject who had responded that they were unequal, and the two were then asked to arrive at agreement. Results showed that younger children rely on external features of a situation in justifying their beliefs. Gender differences in conversations suggest younger children have difficulty differentiating status and knowledge attributes of authority. Older children displayed an awareness of self as a necessarily autonomous element in the process of knowledge acquisition. Unexpected gender effects of stimulus familiarity in the process of persuasion are probably due to differences in subjects' behavioural styles.     

Cultural differences in distraction processing: influence of context at retrieval

Cultural differences in information processing affect perceptual judgment, attention, and memory. We investigated whether cultural differences in processing patterns, specifically East Asian participants’ tendency to encode holistically, compared to Western tendencies to process analytically, affect performance on an implicit memory test. First, participants completed a 1-back task on pictures with superimposed distracting words. After a delay filled with a computerised Corsi block task, they performed a word fragment task in which some fragments could be completed with the distracting words from the 1-back task. Critically, fragments were presented with the same pictures as previously seen (matched condition), with no pictures (control condition), or with pictures from other trials on the 1-back task (mismatched condition). Non-Asian Canadian participants showed virtually no priming for distraction, independent of the reinstatement of encoding context. East Asian Canadian participants showed superior priming for fragments that had been paired with their original pictures. They did not show evidence of a detriment for the mismatched, relative to control, condition.     

Baseline differences,attention, and age differences in time-sharing performance

The purpose of this experiment was to determine whether age differences noted when two tasks are performed concurrently can be accounted for in terms of age differences in single task baseline performance. Two groups of 12 8-year-olds and one group of 12 13-year-olds performed a compensatory tracking task and an auditory matching task, first alone and then time shared. The 8- and 13-year-old baseline groups performed baseline trials on each task prior to time-sharing trials. Each training group 8-year-old was randomly paired with a 13-year-old and given sufficient single task practice before time sharing to equate the 8- and 13-year-old pair members' baselines on both tasks. Results showed trained 8-year-olds to be indistinguishable from 13-year-olds in time sharing, whereas the 8-year-old baseline group showed significantly greater decrements in time-sharing and higher baseline scores on both tasks. These data provide support for the hypothesis that time-shared performance is directly related to level of baseline performance.     

Age differences in reasons for exercising

We tested the hypothesis that there are age-related differences in reasons for exercising. Adults (n=461), ranging in age from 18 to 86, were asked to indicate if they had considered different types of consequences in their exercise decisions, and how important they thought those consequences were to consider. A three-factor consequence measure examined individuals’ consideration and importance evaluations of various categories of exercise consequences. Results provided mixed support for the hypotheses that younger individuals exhibit greater concern for interpersonal attraction outcomes, while older individuals exhibit greater concern for health outcomes. These results have implications for designing educational and motivational training programs.
