The dimensionality of the remember-know task: a state-trace analysis

This article addresses the issue of whether the remember-know (RK) task is best explained by a single-process or a dual-process model. All single-process models propose that remember and know responses reflect different levels of a single strength-of-evidence dimension. Thus, across conditions in which response criteria are held constant, these models predict that the RK task is unidimensional. Many dual-process models propose that remember and know responses reflect two qualitatively distinct processes underlying recognition memory, often characterized as recollection and familiarity. These models predict that the RK task is bidimensional. Using data from 37 studies, the author conducted a state-trace analysis to determine the dimensionality of the RK task. In those studies, non-memory-related differences between conditions were eliminated via decision criteria constrained to be constant across all levels of the independent variables. The results reveal little or no evidence of bidimensionality and lend additional support to the unequal-variance signal detection model. Other arguments supporting a bidimensional interpretation are examined, and the author concludes there is insufficient evidence for the RK task to be used to identify qualitatively different memory components.     

Accurate reaching after active but not passive movements of the hand: evidence for forward modeling

Converging behavioral findings support recent models of motor control suggesting that estimates of the future positions of a limb as well as the expected sensory consequences of a planned movement may be derived, in part, from efference copies of motor commands. These estimates are referred to as forward models. However, relatively little behavioral evidence has been obtained for proposed forward models that provide on-line estimates of current position. We report data from a patient (JD) who reached accurately to visualized targets with and without vision of her hand despite substantial proprioceptive loss. Additionally, we administered a double-start reaching test to examine the possibility that efference copy information could be used to estimate current limb position. JD reached accurately, without vision, to a final target after actively reaching to a landmark, but exhibited severely impaired reaching after passive movements to the landmark. This finding suggests that forward modeling of efference copy signals may provide relatively accurate estimates of current limb position for the purpose of motor planning. The possibility that such estimates may also contribute to the awareness of body position and to self-recognition is discussed.     

Child Abuse—Suicide Resilience Link in African American Women: Interpersonal Psychological Mediators

The interpersonal-psychological theory of suicidal behavior (IPTS) is an exemplary model for understanding the desire for suicidal behavior. As such, it is important to explore its applicability in ethnoracial minority groups at increasing risk for suicidal behavior, such as low-income, African American women. Guided by the IPTS, the current study used 5 parallel mediation models to examine if there are links between individual types of childhood abuse (physical, sexual, emotional) and suicide resilience, and between cumulative abuse (higher levels of abuse inclusive of all three types, more types of severe levels of abuse) and suicide resilience, and whether the three components of the model (thwarted belongingness, perceived burdensomeness, acquired capability for suicide) mediate these associations. In a sample of low-income, African American women (n = 179), higher levels of each of the 3 types of childhood abuse and cumulative abuse correlated with lower levels of suicide resilience. Parallel mediation analyses using bootstrapping techniques revealed that increased acquired capability for suicide mediated all 5 associations and perceived burdensomeness mediated 3 of the links (emotional abuse, cumulative abuse, and cumulative abuse–severe with suicide resilience). Attention is paid to the clinical implications of the findings in terms of attending to the acquired capability for suicide and suicide resilience in the assessment and treatment of low-income, suicidal, African American women.     

Teachers’ Experience, Attitudes, Feelings and Behavioural Intentions towards Children with Special Educational Needs

This project examined teachers’ attitudes to children with special educational needs. Understanding the implicit and explicit attitudes of teachers is an important precursor to improving teaching practices for children with special needs. Participants (N=77) were pre-service teachers and experienced teachers during in-service training courses. Results showed that behavioural intentions related to explicit rather than implicit attitudes, and that feelings of guilt and anxiety were associated with intentions for negative actions. Profiles of attitudes were substantially similar in terms of personal and teaching experiences. However, attitudes were less positive about children with low social skills and more positive about children with low cognitive skills. Findings have direct application to training teachers of children with special educational needs.     

African-American Partisanship and the Legacy of the Civil Rights Movement: Generational, Regional, and Economic Influences on Democratic Identification, 1973–1994

We explore the importance of generational effects and the changing economic circumstances of Blacks to explain variations over time in the partisan attachments of African Americans. More specifically, we explore whether generational differences have caused the cohorts that came of political age following the Civil Rights movement to be less Democratic than generations that lived through the Civil Rights movement and its aftermath. We find that while life-cycle effects explain a portion of the movement away from the two major parties, generational effects account for the small but significant increase in Republican party identification in the youngest generation. Additionally, living in the South accounts for the steepest gains in political independence. Finally, changing economic influences over time appear to have led poorer Blacks to change from the most likely to the least likely to identify with a major party.     

The Virtue Blind Spot: Do Affective Forecasting Errors Undermine Virtuous Behavior?

Why is it difficult to be virtuous? Although cultural wisdom teaches that cultivating virtue brings happiness—and empirical studies have demonstrated the long‐term benefits of acting virtuously—many people seem to behave as though exercising virtues is difficult, or even painful. When it comes to virtue, any benefits for the self may seem distant: short‐term pain for long‐term gain. We propose, however, that behaving virtuously often provides affective benefits even in the short term, but these benefits are obscured by systematic affective forecasting errors. Using five virtues (humanity, wisdom, courage, temperance, and transcendence), we demonstrate that people tend to feel happier after acting virtuously. We also show that people do not realize that these short‐term emotional benefits will occur; when asked to predict how they will feel, people make inaccurate affective forecasts. We argue that these affective forecasting errors drive people away from the exercise of virtue.     

The importance of contextual variables when judging fairness: An examination of counterfactual thoughts and fairness theory

This research empirically examines the underlying mechanisms of fairness theory (  and ), namely counterfactual thought processes. Study 1 used a policy-capturing design to examine the relative importance of contextual variables in predicting counterfactual thoughts and fairness perceptions. Study 2 utilized a between-subjects design and asked participants to generate their own counterfactuals in response to an unfortunate event. Results of both studies showed that fairness perceptions are influenced by contextual variables (i.e., outcome severity, target knowledge and expertise, sin of commission vs. omission) and counterfactual thinking. Counterfactual thoughts partially mediated the effects of contextual variables and fairness perceptions in Study 1. Exploratory analyses from Study 3 revealed that the measurement of counterfactual thoughts (frequency vs. strength) may capture different underlying constructs. Implications are discussed.     

Effects of Sex and Race of Perpetrator and Method of Killing on Outcome Judgments in a Mock Filicide Case

The present study examined college student mock jurors' judgments of legal insanity, outcome severity, and death-penalty decisions in a filicide case. The sex and race of perpetrator (Black or White) and method of killing (shooting or smothering) were varied in a between-subjects design. A 3-way interaction was found for outcome severity, supporting Jones & Davis' (1965) attributional principle of stronger dispositional attributions for unexpected behaviors. As predicted, White women were judged more severely when they used a gun compared to when they smothered, whereas White men were judged more severely when they smothered compared to when they used a gun. The most severe judgments were made for Black male perpetrators who used a gun. Results are discussed in terms of sex and racial stereotypes.
