Positive Emotion Differentiation: A Functional Approach

While positive emotion can be conceptualized broadly as a response to the potential for reward, the environment offers different kinds of rewards, and these are best approached in somewhat different ways. A functional approach to positive emotion differentiation distinguishes among several different types of rewards with strong implications for adaptive fitness and posits the existence of “discrete” positive emotions that promote an adaptive response to each reward. A taxonomy of eight positive emotions, dubbed the “PANACEAS” taxonomy based on an acronym of the first letter of each of the eight constructs, is presented as an example of this approach. Positive emotion constructs defined through functional analyses are useful for guiding empirical research, especially for identifying prototypical eliciting stimuli, and generating hypotheses about the implications of different positive emotions for a variety of outcomes. Research findings are reviewed that support the importance of positive emotion differentiation in understanding the effects of positive emotions on cognition, physiology, and behavior. Advantages of the functional approach are discussed, as well as implications of the approach for evaluating major theories of the structure of emotion.     

The Importance of Friendship for Youth with Attention-Deficit/Hyperactivity Disorder

It is well-established that youth with attention-deficit/hyperactivity disorder (ADHD) are often peer-rejected and rated by parents, teachers, and observers to have poor social skills, when compared to typically developing peers. Significantly less research, however, has been devoted to the experiences youth with ADHD have in their close friendships. The aim of this article is to draw attention to friendship as a distinct construct from peer rejection and social skills and to summarize what is known about youth with ADHD in their friendships. The potential for stable, high-quality friendships to buffer the negative outcomes typically conferred by peer rejection in this population is discussed. This article concludes with recommendations for interventions that specifically target improving the close friendships of youth with ADHD as a treatment strategy.     

Neural activation patterns during retrieval of schema‐related memories: differences and commonalities between children and adults

Schemas represent stable properties of individuals’ experiences, and allow them to classify new events as being congruent or incongruent with existing knowledge. Research with adults indicates that the prefrontal cortex (PFC) is involved in memory retrieval of schema‐related information. However, developmental differences between children and adults in the neural correlates of schema‐related memories are not well understood. One reason for this is the inherent confound between schema‐relevant experience and maturation, as both are related to time. To overcome this limitation, we used a novel paradigm that experimentally induces, and then probes for, task‐relevant knowledge during encoding of new information. Thirty‐one children aged 8–12 years and 26 young adults participated in the experiment. While successfully retrieving schema‐congruent events, children showed less medial PFC activity than adults. In addition, medial PFC activity during successful retrieval correlated positively with children's age. While successfully retrieving schema‐incongruent events, children showed stronger hippocampus (HC) activation as well as weaker connectivity between the striatum and the dorsolateral PFC than adults. These findings were corroborated by an exploratory full‐factorial analysis investigating age differences in the retrieval of schema‐congruent versus schema‐incongruent events, comparing the two conditions directly. Consistent with the findings of the separate analyses, two clusters, one in the medial PFC, one in the HC, were identified that exhibited a memory × congruency × age group interaction. In line with the two‐component model of episodic memory development, the present findings point to an age‐related shift from a more HC‐bound processing to an increasing recruitment of prefrontal brain regions in the retrieval of schema‐related events.     

Function follows form: activation of shape and function features during object identification

Most theories of semantic memory characterize knowledge of a given object as comprising a set of semantic features. But how does conceptual activation of these features proceed during object identification? We present the results of a pair of experiments that demonstrate that object recognition is a dynamically unfolding process in which function follows form. We used eye movements to explore whether activating one object's concept leads to the activation of others that share perceptual (shape) or abstract (function) features. Participants viewed 4-picture displays and clicked on the picture corresponding to a heard word. In critical trials, the conceptual representation of 1 of the objects in the display was similar in shape or function (i.e., its purpose) to the heard word. Importantly, this similarity was not apparent in the visual depictions (e.g., for the target Frisbee, the shape-related object was a triangular slice of pizza, a shape that a Frisbee cannot take); preferential fixations on the related object were therefore attributable to overlap of the conceptual representations on the relevant features. We observed relatedness effects for both shape and function, but shape effects occurred earlier than function effects. We discuss the implications of these findings for current accounts of the representation of semantic memory.     

The Moderating Role of Verbal Aggression on the Relationship Between Parental Feedback and Peer Status Among Children with ADHD

We examined associations between children's sociometric status and (a) observed parental feedback as well as (b) child aggression. Participants were 94 children ages 6-10 (64 male; 44 with ADHD) and their parents. Children's peer status, parental feedback to their children, and child aggression were all assessed during lab-based playgroups of four children and their parents. Parent criticism in front of the child's peers was associated with the child receiving more negative ("disliked") and fewer positive ("liked") nominations, but only for children who displayed aggression; this interaction applied almost exclusively to children with ADHD. Parent praise in front of peers was associated with fewer negative nominations when children displayed low levels of aggression, but more at higher levels. Additional analyses revealed that relationships did not exist in the full sample between privately-given parental feedback and children's peer status. Processes by which peers use overheard adult feedback to inform their assessments of children are discussed.     

Transformed Facial Similarity as a Political Cue: A Preliminary Investigation

Experimental subjects evaluated a political candidate whose face was digitally altered to absorb the subjects' facial structure. For half of the subjects, the photograph of the candidate was morphed such that the image presented was a blend composed of 60% of the unfamiliar Caucasian male and 40% of the subject. For the other half the photograph was unaltered. Given previous research on implicit familiarity (Zajonc, 1968, 1980), we predicted that the morph would advantage the candidate. The results demonstrated no main effect of the similarity manipulation. However, there was a robust similarity by gender interaction. Male subjects evaluated the morphed candidate more favorably than the unaltered photograph, while female subjects rated him more negatively. We discuss potential explanations for this interaction effect and explore the possible implications of facial similarity as a political cue in both high- and low-information elections.     

Qualities of online friendships with different gender compositions and durations.

This study was designed to examine the qualities of online friendships with different gender compositions that had been maintained for varying periods of time. A total of 167 Hong Kong Internet-users rated the qualities of their same-sex and cross-sex online friendships on measures such as intimacy, trust, self-disclosure, and relational satisfaction. A 2 (gender of respondents: male vs. female) x 2 (gender of online friends: same-sex vs. opposite-sex) x 3 (duration of friendships: less than 1 year vs. 1-2 years vs. more than 2 years) factorial design was adopted. MANOVA results reveal the three-way interaction effect on intimacy, trust, and relational satisfaction. Specifically, the qualities of male-female, female-male, and female-female online friendships were generally higher for those with a longer duration than those at the early stage of friendship development. However, the qualities of male-male friendships that had been maintained for more than 2 years were lower than those maintained for 2 years or less. These findings suggest that qualities of online friendships are subject to effects of gender composition and duration. The conceptual implications of these results are discussed.     

Effects of gender and sex role orientation on help-seeking attitudes

This study investigated the effects of gender and sex role orientation (masculinity and femininity) on attitudes toward seeking professional psychological help in a sample of 163 student trainee teachers (52 males and 111 females) in Singapore. The mean age of students was 25.39 years (SD = 3.80). ANOVAs revealed statistically significant main effects for gender and femininity on attitudes toward help-seeking. Specifically, females were reported to have more positive overall attitudes toward professional help-seeking and were more willing to recognize a personal need for professional help compared to males. Femininity significantly influenced students’ level of stigma tolerance. These findings suggest that both gender and sex role orientation play an independent role in influencing help-seeking attitudes. In addition, these variables appear to have a differential impact on different aspects of helpseeking.
