WINDSOR: Windsor improved norms of distance and similarity of representations of semantics

Lexical co-occurrence models of semantic memory form representations of the meaning of a word on the basis of the number of times that pairs of words occur near one another in a large body of text. These models offer a distinct advantage over models that require the collection of a large number of judgments from human subjects, since the construction of the representations can be completely automated. Unfortunately, word frequency, a well-known predictor of reaction time in several cognitive tasks, has a strong effect on the co-occurrence counts in a corpus. Two words with high frequency are more likely to occur together purely by chance than are two words that occur very infrequently. In this article, we examine a modification of a successful method for constructing semantic representations from lexical co-occurrence. We show that our new method eliminates the influence of frequency, while still capturing the semantic characteristics of words.     

Memory fragments as components of autobiographical knowledge

Adults described and dated two kinds of personal remembrances: a fragment—a memory moment that is largely bereft of context—and an episodic, personal event memory—a narrative that consists of a number of related events. In Experiment 1 subjects reported memories from when they were 0–8 years of age and in Experiment 2, from when they were 0–16 years of age. Fragments were judged to be older than event memories, especially in Experiment 2 where the estimated ages of most fragments were from 0 to 8 years and of most episodic memories, from 8 to 16 years. Ratings of various features of the two kinds of memories also differed. We conclude that isolated memory moments possess validity and that although they are most likely to arise when the autobiographical memory system is not fully developed, they can also originate during a time when it is.

Human proactive aggression: association with personality disorders and psychopathy

Aggressive behaviors can be divided into two categories: reactive and proactive. Reactive aggressive behaviors occur in response to a stimulus or provocation. Proactive aggressive behaviors occur without provocation and are goal directed. A number of findings have suggested that individuals displaying proactive aggression may be discerned from individuals not displaying proactive aggression on measures of personality, psychopathology and psychopathy as well as in aggressive histories and type and severity of aggressive behaviors committed. In this study, subjects were recruited from a large urban community and classified as proactive (n = 20), reactive-only (n = 20) or nonaggressive (n = 10) based on laboratory behavioral testing. Subjects were administered a battery of questionnaires and structured interviews pertaining to personality disorders and psychopathy. It was hypothesized that proactive aggressive subjects would show greater numbers of personality disorders and have greater psychopathy relative to reactive-only and nonaggressive subjects. These hypotheses were supported. These results suggest that proactive aggression may be identified in a laboratory-based task, and differences between proactive and reactive-only aggressors can be detected.     

Daily and trait rumination: diurnal cortisol patterns in adolescent girls

Rumination is a maladaptive form of emotion regulation associated with psychopathology. Research with adults suggests that rumination covaries with diurnal cortisol rhythms, yet this has not been examined among adolescents. Here, we examine the day-to-day covariation between rumination and cortisol, and explore whether trait rumination is associated with alterations in diurnal cortisol rhythms among adolescent girls. Participants (N?=?122) provided saliva samples 3 times per day over 3 days, along with daily reports of stress and rumination, questionnaires assessing trait rumination related to peer stress, and diagnostic interviews assessing depression and anxiety. Greater rumination than usual during the day was associated with lower cortisol awakening responses the following morning, but this effect was not significant after accounting for wake time and an objective measure of adherence to the saliva sampling protocol. Trait rumination was associated with lower average cortisol levels at waking and flatter diurnal slopes, accounting for wake time, protocol compliance, and other factors. These patterns may help to explain why rumination is related to the development of psychopathology.     

The Problematization of Sexuality among Women Living with HIV and a New Feminist Approach for Understanding and Enhancing Women’s Sexual Lives

In the context of HIV, women’s sexual rights and sexual autonomy are important but frequently overlooked and violated. Guided by community voices, feminist theories, and qualitative empirical research, we reviewed two decades of global quantitative research on sexuality among women living with HIV. In the 32 studies we found, conducted in 25 countries and composed mostly of cis-gender heterosexual women, sexuality was narrowly constructed as sexual behaviours involving risk (namely, penetration) and physiological dysfunctions relating to HIV illness, with far less attention given to the fullness of sexual lives in context, including more positive and rewarding experiences such as satisfaction and pleasure. Findings suggest that women experience declines in sexual activity, function, satisfaction, and pleasure following HIV diagnosis, at least for some period. The extent of such declines, however, is varied, with numerous contextual forces shaping women’s sexual well-being. Clinical markers of HIV (e.g., viral load, CD4 cell count) poorly predicted sexual outcomes, interrupting widely held assumptions about sexuality for women with HIV. Instead, the effects of HIV-related stigma intersecting with inequities related to trauma, violence, intimate relations, substance use, poverty, aging, and other social and cultural conditions primarily influenced the ways in which women experienced and enacted their sexuality. However, studies framed through a medical lens tended to pathologize outcomes as individual “problems,” whereas others driven by a public health agenda remained primarily preoccupied with protecting the public from HIV. In light of these findings, we present a new feminist approach for research, policy, and practice toward understanding and enhancing women’s sexual lives—one that affirms sexual diversity; engages deeply with society, politics, and history; and is grounded in women’s sexual rights.     

Important Elements of Aftercare Services for Youth Departing Group Homes

Aftercare services have been suggested to improve the outcomes of youth who depart group homes. The purpose of this study was to collect views from social service agency leaders about the aftercare supports they believed were most important for youth departing group homes. This project used a survey method and gathered views from 38 agency leaders who were 28–66 years of age, with an average of 21 years of experience working with residential care programs in 23 states across the United States. Participants ranked seven support domains (i.e., family, education, mental health, relationships, physical health, safety, and independent living) and rated 56 specific aftercare supports based on importance for youth who were departing group homes and returning to their homes/schools prior to high school graduation. Results suggested family, safety, and mental health supports were the most important domains of support for aftercare. Specific aftercare items that were rated critically important included support for self-harm/suicidal thoughts, accessing mental health services, coping with trauma, and managing medication for behavior/mental health. Tables are provided for the complete list of 56 specific support ratings. The findings are summarized and limitations are discussed. Also included are the implications the findings could have regarding future research on the design of aftercare services.     

Ethical Behavioral Intention in an Academic Setting: Models and Predictors

This study examines the theory of planned behavior (TPB) and the multidimensional ethics scale (MES). Variables from both are included to determine which ones significantly correlate with student ethical behavioral intention in an academic setting. Using a survey, responses are collected from undergraduate business students from two southwestern universities in the United States using a scenario-based approach, looking at individual situations and group situations. SmartPLS was used to assess the results for four scenarios. From the theory of planned behavior, attitude was a significant predictor of behavioral intention across all four scenarios while subjective norm was significant in one scenario. From the multidimensional ethics scale, moral equity and relativism were significant in one group scenario while moral equity and utilitarianism were each significant in an individual scenario. The findings indicate support for the use of the TPB and the MES when exploring ethics in an academic setting and for the need to study both individual and group situations. A discussion of the findings and implications is given.     

Remembering what one intended to forget: the lack of directed forgetting effects in implicit memory

The results of previous studies on directed forgetting effects in implicit memory have led to the conclusion that the underlying mechanism for such effects is an inhibition of retrieval or an encoding difficulty. Differences in procedure and stimuli may contribute to these different conclusions. In 2 studies we standardized the procedure while varying the stimuli. As in previous research, directed forgetting results were obtained for direct memory tasks. However, the magnitude of the directed forgetting effect varied with the stimuli. In Experiments 1 and 2, medium- and low-frequency to-be-remembered (R) and to-be-forgotten (F) words appeared to be equally accessible using the indirect task. In Experiment 3, we devised a procedure in which a single stem could lead to an R-word or F-word, but space was provided for only one word. In that way, we could examine the relative accessibility of R- and F-words. Results are discussed in light of Mandler's (1980) conceptualization of the contributions of identification and familiarity to memory retrieval processes.     

Boys' and girls' use of cognitive strategy when learning to play video games

The authors examined gender differences in the cognitive strategies that children use when they learn how to play a video game. They interviewed 2nd- and 5th-grade boys and girls about how often they played video games and what they did "when learning how to play a video game." The children's responses to the latter question were categorized as either internally or externally oriented (i.e., reading a manual vs. asking for help, respectively). The results indicated that more frequent players and older children were more likely to cite internally based strategies. No main effects of gender were found for the proportions of the internally vs. externally based strategies that were cited.     

An Empowerment Evaluation Model for Sexual Assault Programs: Empirical Evidence of Effectiveness

Using an empowerment evaluation approach, the Sexual Assault and Rape Prevention (SARP) Evaluation Project brought together university researchers, public health evaluators, state funders, and program staff to provide evaluation training and consultation to all state-funded rape prevention and victim services programs in Michigan. In this paper, the specific activities of the SARP project are described, and process and outcome data are presented that address the effectiveness of this empowerment evaluation approach. Based on subjective reports from program staff and objective data obtained from state funders, results suggest that this evaluation model was successful in helping 90% of the prevention programs and 75% of the victim services programs successfully develop and launch program evaluations. One-year follow-up data indicate that 90% of the programs had sustained their evaluation efforts after the formal work of the SARP project had ended.
