REDUCTIONS IN SELF-INJURY PRODUCED BY TRANSCUTANEOUS ELECTRICAL NERVE STIMULATION

Transcutaneous electrical nerve stimulation is used to reduce pain but also may be useful for self-injurious behavior (SIB). In the current investigation, a microcurrent electromedical device, classified as a transcutaneous electrical nerve stimulator (TENS), was applied with a man with Down syndrome who displayed SIB that persisted in the absence of social contingencies. Although clinically significant results were not maintained, a clear difference in the rates of SIB during active and inactive TENS was observed.     

Identifying Causes of Disagreement Between Self-Reports and Spouse Ratings of Personality

Self-reports and spouse ratings of personality traits typically show less-than-perfect agreement, but powerful moderators of agreement have not yet been identified. In Study 1, 47 married couples completed the Revised NEO Personality Inventory to describe themselves and their spouses. Extent of agreement was not consistently moderated by response sets; the age, intelligence, or education of the respondent; or the length or quality of the relationship. In Study 2 these couples were interviewed about reasons for substantial disagreements, and an audiotape was content-analyzed. Sixteen reasons were reliably coded, including idiosyncratic understanding of items, reference to different time frames or roles, and unavailability of covert experience to the spouse. Faking good, assumed similarity, and other variables prominent in the psychometric literature were relatively unimportant. Findings (1) suggest that attempts to improve the validity of self-reports and ratings may need to be refocused and (2) underscore the desirability of routinely obtaining multiple sources of information on personality.     

Openness to Experience and Development of Adult Identity

ABSTRACT The formation of ego identity through exploration of alternatives and formation of commitments is a central issue in the transition from adolescence to adulthood (Erikson, 1959, Waterman, 1982) In 59 adults ranging in age from 18 to 30, independent identity scales were found to be positively correlated with age The construct of openness to experience was hypothesized to account for individual differences in identity development As predicted, openness to experience was positively correlated with ratings of current and past identity exploration, and negatively related to intensity of identity commitment A comparison of two methods of measuring ego identity showed that identity rating scales provide a more differentiated assessment of psychosocial development than does the identity status scoring method     

Worlds within worlds: a strategy for using interpretative phenomenological analysis with focus groups

There is increasing interest in applying interpretative phenomenological analysis (IPA) to focus group data and in developing appropriate strategies for doing so. These strategies should exploit the unique features of focus groups, which provide a rich canvas of experiences not seen in individual interviews, while remaining true to the personal, phenomenological perspective of IPA. We present a four-stage approach with specific group focused analytical strategies: looking for “groupness,” clustering reoccurring group interactions, identifying interactional relationships, and incorporating group elements into an analysis. These stages are illustrated with worked examples developed while working with data from focus groups of women with gynaecological cancer discussing a yoga intervention, and explain how these can enrich our understanding of participants’ lived experiences. This approach demonstrates a suggested framework for developing IPA themes from focus group data by analysing and interpreting the group setting. We discuss links to psychological concepts, potential applications and limitations. This empirically based methodology is presented as a practical guide for other researchers grappling with this type of data.     

Selective spatial enhancement: Attentional spotlight size impacts spatial but not temporal perception

An important but often neglected aspect of attention is how changes in the attentional spotlight size impact perception. The zoom-lens model predicts that a small (“focal”) attentional spotlight enhances all aspects of perception relative to a larger (“diffuse” spotlight). However, based on the physiological properties of the two major classes of visual cells (magnocellular and parvocellular neurons) we predicted trade-offs in spatial and temporal acuity as a function of spotlight size. Contrary to both of these accounts, however, across two experiments we found that attentional spotlight size affected spatial acuity, such that spatial acuity was enhanced for a focal relative to a diffuse spotlight, whereas the same modulations in spotlight size had no impact on temporal acuity. This likely reflects the function of attention: to induce the high spatial resolution of the fovea in periphery, where spatial resolution is poor but temporal resolution is good. It is adaptive, therefore, for the attentional spotlight to enhance spatial acuity, whereas enhancing temporal acuity does not confer the same benefit.     

Beyond Abstinence: An Examination of Psychological Well-Being in Members of Narcotics Anonymous

While a growing body of literature supports the role of mutual help organizations in helping members achieve abstinence, fellowships other than Alcoholics Anonymous and outcomes beyond abstinence have been studied far less often. The current study examined recovery-related correlates of psychological well-being in a sample of Narcotics Anonymous (NA) members. Participants (N = 128) were self-identified NA members from across the United States who completed an online survey assessing an array of psychosocial outcomes. Hierarchical regression models assessed whether abstinence duration and other recovery-related variables accounted for significant incremental variance in psychological well-being, over and above several covariates. As a block, abstinence duration and the recovery predictors accounted for significant incremental variance in three of four psychological well-being domains. As a complement to studies on short-term benefits of mutual help organizations, these data suggest ongoing recovery involvement may be positively associated with subjective psychological well-being in NA members.     

Exploring the Relationship between Adolescent Activities and Choice of Graduate School Discipline: Implications for Creativity Development

The relationship between adolescent extra‐curricular activities and choice of graduate‐education field was examined among students from three fields of study, science (n = 12), art (n = 12), and education (n = 14), using qualitative and quantitative methods. Results of profile analysis indicated that the different majors participated in stereotypically varying activities when they were adolescents. Science majors generally participated in mathematics and science activities during adolescence. Art majors generally participated in theater and music activities, and education majors tended to have participated in social leadership and educational activities. Interviews with the participants supported these findings and provided a more comprehensive discussion of these tendencies. While in high school, the participants had many influences when determining a field of study. Using personal happiness as a guide, the participants chose activities and ultimately graduate‐level majors that reflected their interests. It was concluded that adolescent extra‐curricular activities are important in the development of interest in creatively talented individuals and may lead to graduate field selection.     

Identifiability of Diagnostic Classification Models

Diagnostic classification models (DCMs) are important statistical tools in cognitive diagnosis. In this paper, we consider the issue of their identifiability. In particular, we focus on one basic and popular model, the DINA model. We propose sufficient and necessary conditions under which the model parameters are identifiable from the data. The consequences, in terms of the consistency of parameter estimates, of fulfilling or failing to fulfill these conditions are illustrated via simulation. The results can be easily extended to the DINO model through the duality of the DINA and DINO models. Moreover, the proposed theoretical framework could be applied to study the identifiability issue of other DCMs.     

Collectives’ and individuals’ obligations: a parity argument

Individuals have various kinds of obligations: keep promises, don’t cause harm, return benefits received from injustices, be partial to loved ones, help the needy and so on. How does this work for group agents? There are two questions here. The first is whether groups can bear the same kinds of obligations as individuals. The second is whether groups’ pro tanto obligations plug into what they all-things-considered ought to do to the same degree that individuals’ pro tanto obligations plug into what they all-things-considered ought to do. We argue for parity on both counts.
