Chronic exposure to violent video games is not associated with alterations of emotional memory

Although acute effects of violent video game (VVG) exposure on affect and behaviour have been studied extensively, less is known about VVG effects on cognition. The present study examined whether chronic exposure to VVGs was associated with alterations in emotional long‐term memory. Participants completed an old‐new recognition task with 300 pictures of scenes ranging in emotion (negative, neutral and positive). We analysed accuracy and reaction time data using diffusion modelling to test a desensitization hypothesis. According to this hypothesis, VVG players would show reduced memory or a less liberal response bias for negative stimuli, compared with nonplayers. Contrary to the desensitization hypothesis, VVG exposure was not associated with differences in memory or response bias. This result suggests that, unlike other cognitive domains, long‐term memory may be robust to deleterious influences of chronic VVG exposure. Copyright © 2010 John Wiley & Sons, Ltd.     

Acquired equivalence between stimuli trained in the same context

The role of context was examined in human acquired equivalence. Participants were trained on two conditional discriminations. In the first conditional discrimination, if sample A1 was presented, choice of comparison B1, but not B2, was correct, and if sample A2 was presented, choice of comparison B2, but not B1, was correct. In the second conditional discrimination, if sample X1 was presented, choice of comparison Y1, but not Y2, was correct, and if sample X2 was presented, choice of comparison Y2, but not Y1, was correct. In each conditional discrimination, one of the conditional relations was trained in context 1 (e.g., A1 → B1 and X1 → Y1) and the other was trained in context 2 (i.e., A2 → B2 and X2 → Y2). On test trials, when conditional stimuli from the two conditional discriminations were interchanged (e.g., sample A1 was presented with comparisons Y1 and Y2) and were presented in a neutral context, positive transfer resulted. That is, in the absence of the training context, stimuli that shared a common context on different trials in training came to be treated as equivalent.     

The Fabric of Thought: Priming Tactile Properties During Reading Influences Direct Tactile Perception

The present studies examined whether implied tactile properties during language comprehension influence subsequent direct tactile perception, and the specificity of any such effects. Participants read sentences that implicitly conveyed information regarding tactile properties (e.g., Grace tried on a pair of thick corduroy pants while shopping) that were either related or unrelated to fabrics and varied in implied texture (smooth, medium, rough). After reading each sentence, participants then performed an unrelated rating task during which they felt and rated the texture of a presented fabric. Results demonstrated that the texture properties implied in sentences influence direct tactile perception. Specifically, after reading about a smooth or rough texture, subsequent fabric ratings became notably smoother or rougher, respectively. However, we also show that there was some specificity to these effects: Fabric‐related sentences elicited more specific and interactive effects on subsequent ratings. Together, we demonstrate that under certain circumstances, language comprehension can prime tactile representations and affect direct tactile perception. Results are discussed with regard to the nature and scope of multimodal mental simulation during reading.     

An Examination of the Latent Structure of the Difficulties in Emotion Regulation Scale

The Difficulties in Emotion Regulation Scale (DERS; Gratz and Roemer, Journal of Psychopathology and Behavioral Assessment 26:41?C54, 2004) is a popular multidimensional self-report measure of emotion regulation. The present study sought to examine the latent factor structure of the DERS. An examination of latent factor intercorrelations and a higher-order confirmatory factor analysis (CFA) suggested that the DERS-AWARENESS dimension may not represent the same higher-order emotion regulation construct as the other five DERS dimensions. Furthermore, findings supported the adequacy of a revised five-factor model of the DERS in which the AWARENESS dimension was removed. This revised DERS total scale did not diminish concurrent relations between the DERS and outcomes relevant to the emotion regulation domain (i.e., depression, anxiety, posttraumatic stress symptoms). Implications for the conceptualization and assessment of emotion regulation are discussed.     

Humans and monkeys show similar skill in estimating uncertain outcomes

When information is incomplete but a choice must be made, individuals sometimes can rely on past experiences to help them assess uncertain outcomes in terms of the probabilities of payoffs. Monkeys (Cebus apella) and humans (Homo sapiens) were presented with a test in which they first made quantity judgments between two clear options. Then they made choices in which only one option was visible, and they had to estimate the quantity for the other option. Both species were guided by the past outcomes, as they shifted from selecting the known option to selecting the unknown option at the point at which the known option went from being greater than the average rate of return to being less than the average rate of return. This comparability across species suggests that tallying ongoing average rates of return from repeated choices occurs spontaneously and likely serves an adaptive purpose when dealing with uncertainty in the environment.     

The comprehension of anomalous sentences: evidence from structural priming

We report three experiments investigating how people process anomalous sentences, in particular those in which the anomaly is associated with the verb. We contrast two accounts for the processing of such anomalous sentences: a syntactic account, in which the representations constructed for anomalous sentences are similar in nature to the ones constructed for well-formed sentences; and a semantic account, in which the representations constructed for anomalous sentences are erroneous, or altogether missing, and interpretation is achieved on the basis of semantic representations instead. To distinguish between these accounts, we used structural priming. First, we ruled out the possibility that anomaly per se influences the magnitude of the priming effect: Prime sentences with morphologically incorrect verbs produced similarly enhanced priming (lexical boost) to sentences with the same correct verbs (Exp. 1). Second, we found that prime sentences with a novel verb (Exp. 2) or a semantically and syntactically incongruent verb (Exp. 3) produced a priming effect, which was the same as that produced by well-formed sentences. In accord with the syntactic account, we conclude that the syntactic representations of anomalous sentences are similar to those constructed for well-formed sentences. Our results furthermore suggest that lexically-independent syntactic information is robust enough to produce well-formed syntactic representations during processing without requiring aid from lexically-based syntactic information.     

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.     

Friendship and Romantic Stressors and Depression in Emerging Adulthood: Mediating and Moderating Roles of Attachment Representations

Although friendships and romantic relationships represent important social relationships during emerging adulthood, problems stemming from these relationships may also pose a threat to emerging adults’ psychological functioning (Collins and Madsen in Handbook of personal relationships. Cambridge University Press, New York, pp 191–209, 2006; La Greca and Moore Harrison in J Clin Child Adolesc Psychol 34(1): 49–61, 2005). Thus, investigating relational stressors in friendships and romantic relationships is an important step toward understanding emerging adults’ psychological adjustment. This study focused on examining the relationship between relational stressors and depression, and the mediating and moderating roles of relationship-general attachment representations between these constructs. Data were collected from 164 emerging adults attending a Midwestern university. In partial support of our hypotheses, emerging adults’ attachment anxiety mediated the relationship between experiences of friendship and romantic stressors and depression; this result, however, was not found for attachment avoidance. Furthermore, results showed that attachment avoidance and anxiety moderated the relationship between friendship stressors and depression in emerging adulthood. Supporting our hypothesis, friendship stressors were predictive of higher levels of depression only for emerging adults who were high in attachment avoidance or anxiety. Future research and practical implications are discussed.     

STABILITY OF BIOLOGICAL FATHER PRESENCE AS A PROXY FOR FAMILY STABILITY: CROSS‐RACIAL ASSOCIATIONS WITH THE LONGITUDINAL DEVELOPMENT OF EMOTION REGULATION IN TODDLERHOOD

The current study, utilizing data from the National Early Head Start Research and Evaluation Project (Love et al., 2005) explored the relationship between biological father presence and emotion regulation over toddlerhood among children from low‐income families. Conceptualizing biological father presence as a proxy for family role development, results are interpreted from a role development theoretical perspective. The latent growth curve model was compared based on child ethnoracial status (African American, Caucasian, Hispanic) and child gender. Consistent biological father presence was associated with toddlers’ regulatory development across toddlerhood, and this relationship was most robust among Caucasian toddlers as compared to African American toddlers. Findings for Hispanic toddlers were not significantly different from those of Caucasian or African American families. Results bolster the literature on father presence and child outcomes. Analyses address consistency in father presence as a proxy for coherent role development and define a link between consistent father presence and children's regulatory development, demonstrating ethnoracial differences which are likely attributed to the social construction of family roles.
