At the same time or apart in time? The role of presentation timing and retrieval dynamics in generalization

Several bodies of research have found different results with regard to presentation timing, categorization, and generalization. Both presenting instances at the same time (simultaneous) and presenting instances apart in time (spacing) have been shown to facilitate generalization. In this study, we resolved these results by examining simultaneous, massed, and spaced presentations in 2-year-old children's (N = 144) immediate and long-term performance on a novel noun generalization task. Results revealed that, when tested immediately, children in the simultaneous condition outperformed children in all other conditions. However, when tested after 15 min, children in the spaced condition outperformed children in all other conditions. Results are discussed in terms of how retrieval dynamics during learning affect abstraction, retention, and generalization across time.     

Helping or Hovering? The Effects of Helicopter Parenting on College Students’ Well-Being

Parental involvement is related to many positive child outcomes, but if not developmentally appropriate, it can be associated with higher levels of child anxiety and depression. Few studies have examined the effects of over-controlling parenting, or “helicopter parenting,” in college students. Some studies have found that college students of over-controlling parents report feeling less satisfied with family life and have lower levels of psychological well-being. This study examined self-determination theory as the potential underlying mechanism explaining this relationship. College students (N = 297) completed measures of helicopter parenting, autonomy supportive parenting, depression, anxiety, satisfaction with life, and basic psychological needs satisfaction. Students who reported having over-controlling parents reported significantly higher levels of depression and less satisfaction with life. Furthermore, the negative effects of helicopter parenting on college students’ well-being were largely explained by the perceived violation of students’ basic psychological needs for autonomy and competence.

Socioeconomic status modifies heritability of IQ in young children

Scores on the Wechsler Intelligence Scale for Children were analyzed in a sample of 7-year-old twins from the National Collaborative Perinatal Project. A substantial proportion of the twins were raised in families living near or below the poverty level. Biometric analyses were conducted using models allowing for components attributable to the additive effects of genotype, shared environment, and nonshared environment to interact with socioeconomic status (SES) measured as a continuous variable. Results demonstrate that the proportions of IQ variance attributable to genes and environment vary nonlinearly with SES. The models suggest that in impoverished families, 60% of the variance in IQ is accounted for by the shared environment, and the contribution of genes is close to zero; in affluent families, the result is almost exactly the reverse.     

Forward and backward recall: different response time patterns,same retrieval order

How do people retrieve information in forward and backward recall? To address this issue, we examined response times in directional recall as a function of serial position and list length. Participants memorized lists of four to six words and entered responses at the keyboard. Recall direction was postcued. Response times exhibited asymmetry in terms of direction. In forward recall, response times peaked at the first position, leveling off for subsequent positions. Response times were slower in backward recall than in forward recall and exhibited an inverse U-shaped function with an initial slowdown followed by a continuous speedup. These asymmetries have implications for theoretical models of retrieval in serial recall, including temporal-code, rule-based, and network models. The response time pattern suggests that forward recall proceeds in equal steps across positions, whereas backward recall involves repeated covert cycles of forward recall. Thus, retrieval in both directions involves a forward search.     

Psychopathy and COVID-19: Callousness,impulsivity, and motivational reasons for engaging in prevention behavior

Two direct replication studies were conducted to investigate the associations of psychopathic traits with engagement in COVID-19 prevention behavior and motivational reasons for engaging in such behavior. College undergraduate students completed two self-report measures of psychopathic traits based on the four-factor conceptualization of psychopathy (callous affect, manipulative tendency, erratic lifestyle, criminal tendency) and the triarchic conceptualization of psychopathy (meanness, disinhibition, boldness). Participants then reported the degree to which they engaged in COVID-19 prevention behavior currently and in the past, and reported their self-focused and other-focused motivational reasons for doing so. Results aggregated across both studies (N = 292) revealed that traits reflecting emotional callousness and impulsivity independently predicted lower levels of other-focused reasons for engaging in prevention behavior. Moreover, controlling for other-focused reasons appreciably reduced negative associations of emotional callousness and impulsivity with prevention behavior. The results provide insight into points of convergence in conceptualization and measurement of psychopathy from multiple theoretical perspectives and the importance of considering the impact of divisive personality traits on motivation to protect others during pandemics.     

Primary, secondary, and emotional control across adulthood

Schulz and Heckhausen (1996) have recently formulated a theory of successful aging that centers on perceptions of control as a major theme in the developmental process. They suggest primary control is a universal phenomenon and that people will strive for primary control over secondary control. Secondary control mechanisms, on the other hand, may serve to mediate losses in primary control. This study evaluates the relationship between primary and secondary control among 327 men and women, by administering a general sense of control scale and an emotion control measure with four sub-scales. Consistent with previous research, both age and gender differences were found in primary and secondary control. The results of this study provide support for the theory of emotional selectivity which postulates that as people age they are more able to regulate their emotions, thereby directing energies at increasing secondary control mechanisms (Carstensen, 1986).     

Eye movement Responses of Repressors and Sensitizers to a stressful film

Groups scoring high, intermediate or low on the Byrne R-S Scale viewed an industrial accident film while horizontal eye movements were assessed by means of infrared corneal reflection. Neutral and stressful film segments were scored in terms of deviations from the center of the perceptual field (point of looking scores), and the standard deviations of these scores were calculated as an index of perceptual scanning. A stressful segment was also dichotically scored as to whether the point of looking was on or off dominant elements of the scene. Results indicated that Repressors and Sensitizers had equivalent levels of perceptual scanning (and both significantly higher than Intermediates' level) independent of film segment content, but that they differed in on/off and average point of looking for the stressful segment such that Repressors were avoiding stressful content. These data suggest that relatively high perceptual scanning can be an avoidant defensive style of attending to dynamic stimulus displays. The issue of adaptiveness of responding is considered.     

What Predicts Attitudes toward Transgender and Nonbinary People? An Exploration of Gender,Authoritarianism, Social Dominance,and Gender Ideology

Transgender and nonbinary (TGNB) people face discrimination based on negative societal attitudes toward TGNB identities. Our study explored factors contributing to negative TGNB attitudes, including participants’ gender, age, religion, right-wing authoritarianism (RWA), social dominance orientation (SDO), and adherence to traditional gender ideologies. Our sample of 808 U.S. Mechanical Turk participants completed measures of RWA, SDO, traditional masculinity and femininity, and transgender attitudes and beliefs. Because TGNB people have diverse identities, we modified the transgender attitudes and beliefs scale to measure attitudes toward trans man, trans woman, and nonbinary targets instead of the single “transgender” umbrella. Results of multiple regression analyses indicated that gender was a significant predictor of attitudes toward trans men and trans women. Higher levels of RWA, traditional masculinity, and anti-egalitarianism (a domain of SDO) predicted negative attitudes toward all TGNB identities, with RWA generally being the strongest predictor. Traditional femininity and the dominance domain of SDO did not significantly contribute to our predictive model for most groups, although we were surprised to find that for nonbinary people, higher levels of traditional femininity predicted positive attitudes. These results can inform targeted interventions aimed at reducing transprejudice.
