Benchmark Memories in Adulthood: Central Domains and Predictors of Their Frequency

This study extended earlier research on the reminiscence bump phenomenon in autobiographical memory by examining the central domains and predictors of benchmark memories from a life history timeline and from three selected significant events. Memories elicited by these methods demonstrated the reminiscence bump as occurring in early adulthood. The central domains representing this era involved events with family and relationships followed by those related to education and work. Individual differences in socio-emotional variables associated with self and identity formations (i.e., family climate, defensive style, self-complexity, and adult attachment) were associated with the reminiscence bump. These findings support the self-narrative hypothesis that the reminiscence phenomenon is related to the process of identity formation in late adolescence and early adulthood.     

Effects of interactive physical-activity video-game training on physical and cognitive function in older adults

The purpose of the present study was to assess the potential of exergame training based on physically simulated sport play as a mode of physical activity that could have cognitive benefits for older adults. If exergame play has the cognitive benefits of conventional physical activity and also has the intrinsic attractiveness of video games, then it might be a very effective way to induce desirable lifestyle changes in older adults. To examine this issue, the authors developed an active video game training program using a pretest-training-posttest design comparing an experimental group (24 × 1 hr of training) with a control group without treatment. Participants completed a battery of neuropsychological tests, assessing executive control, visuospatial functions, and processing speed, to measure the cognitive impact of the program. They were also given a battery of functional fitness tests to measure the physical impact of the program. The trainees improved significantly in measures of game performance. They also improved significantly more than the control participants in measures of physical function and cognitive measures of executive control and processing speed, but not on visuospatial measures. It was encouraging to observe that, engagement in physically simulated sport games yielded benefits to cognitive and physical skills that are directly involved in functional abilities older adults need in everyday living (e.g., Hultsch, Hertzog, Small, & Dixon, 1999).     

A Multi-informant Multi-Measure Approach to the Two Factor Model of Emotion with Youth

The two-factor model of emotion clarifies the complexities of the relationship between anxiety and depression through their varying associations with positive and negative affect. Although this model’s structure has been studied in children, the lack of parent report measures on model-specific constructs has thus far prevented a multi-informant perspective on the model. Capitalizing on recent advancements in parent report assessment instruments, the present investigation aimed to confirm the two-factor model of emotion per child self-report; expand the model’s applicability to include parent report; and create a combined-informant model with a large number of parent-child dyad pairs (N?=?610). Structural equation modeling demonstrated good fit within parent and child informant models, but diminished fit for the multi-informant model. These results suggest a high degree of robustness with respect to informant type. Implications for the integration of multi-informant assessment information are discussed.     

Should Social Aggression be Considered “Antisocial”?

There is converging evidence that physical aggression and non-aggressive rule-breaking constitute meaningfully distinct, if somewhat overlapping, dimensions of antisocial behavior, with different developmental trajectories, demographic correlates, and etiologies. Social aggression can also be factor-analytically and demographically distinguished from physically aggressive and rule-breaking antisocial behavior. However, there is ongoing debate as to whether social aggression should also be considered “antisocial” in the way the term is commonly understood, given that socially aggressive behaviors are generally legal and nearly normative during adolescence. The current study sought to empirically evaluate the notion that social aggression constitutes a form of antisocial behavior that is separable from other forms of antisocial behavior. We thus conducted a preliminary study to examine whether social aggression was associated with other forms of antisocial behavior and a variety of correlates of antisocial behavior in a sample of 497 undergraduates. Analyses revealed that social aggression was independently associated with other measures of antisocial behavior, substance use and unethical behaviors, as well as the personality traits known to predict current and future antisocial behavior. These associations were particularly pronounced in women. Such findings are consistent with our hypothesis that social aggression constitutes a distinct form of antisocial behavior.     

Chimpanzees and bonobos exhibit divergent spatial memory development

Spatial cognition and memory are critical cognitive skills underlying foraging behaviors for all primates. While the emergence of these skills has been the focus of much research on human children, little is known about ontogenetic patterns shaping spatial cognition in other species. Comparative developmental studies of nonhuman apes can illuminate which aspects of human spatial development are shared with other primates, versus which aspects are unique to our lineage. Here we present three studies examining spatial memory development in our closest living relatives, chimpanzees (Pan troglodytes) and bonobos (P. paniscus). We first compared memory in a naturalistic foraging task where apes had to recall the location of resources hidden in a large outdoor enclosure with a variety of landmarks (Studies 1 and 2). We then compared older apes using a matched memory choice paradigm (Study 3). We found that chimpanzees exhibited more accurate spatial memory than bonobos across contexts, supporting predictions from these species’ different feeding ecologies. Furthermore, chimpanzees – but not bonobos – showed developmental improvements in spatial memory, indicating that bonobos exhibit cognitive paedomorphism (delays in developmental timing) in their spatial abilities relative to chimpanzees. Together, these results indicate that the development of spatial memory may differ even between closely related species. Moreover, changes in the spatial domain can emerge during nonhuman ape ontogeny, much like some changes seen in human children.     

Attitudes about psychotherapy: A qualitative study of introductory psychology students who have never been in psychotherapy and the influence of attachment style

Design: Interviews about attitudes about psychotherapy with 12 undergraduate students who had never been in psychotherapy were analysed using consensual qualitative research. Results: Participants believed that the client role is to disclose, be receptive, and be motivated; that the therapist role is to listen, support, and give advice; and that the therapeutic relationship should be close and personal. Participants had ideas about the benefits (a healing therapeutic relationship, personal and interpersonal changes) and the barriers (self‐stigma and public stigma, difficulty revealing, need to solve problems on own, cost) associated with seeking therapy, and they disliked the idea of being diagnosed. In contrast with participants who were securely attached, those who were insecurely attached more often wanted a professional therapeutic relationship, wanted the therapist to ask questions, mentioned fewer benefits to therapy, and thought that they would have difficulty disclosing to a therapist. Discussion: Implications for changing attitudes about psychotherapy and improving training programs for practitioners are discussed.     

Tactual perception: a review of experimental variables and procedures

This paper reviews the literature on tactual perception. Throughout this review, we will highlight some of the most relevant aspects in the touch literature: type of stimuli; type of participants; type of tactile exploration; and finally, the interaction between touch and other senses. Regarding type of stimuli, we will analyse studies with abstract stimuli such as vibrations, with two- and three-dimensional stimuli, and also concrete stimuli, considering the relation between familiar and unfamiliar stimuli and the haptic perception of faces. Under the "type of participants" topic, we separated studies with blind participants, studies with children and adults, and also performed an overview of sex differences in performance. The type of tactile exploration is explored considering conditions of active and passive touch, the relevance of movement in touch and the relation between haptic exploration and time. Finally, interactions between touch and vision, touch and smell and touch and taste are explored in the last topic. The review ends with an overall conclusion on the state of the art for the tactual perception literature. With this work, we intend to present an organised overview of the main variables in touch experiments, compiling aspects reported in the tactual literature, and attempting to provide both a summary of previous findings, and a guide to the design of future works on tactual perception and memory, through a presentation of implications from previous studies.     

Bibliotherapy for low sexual desire: evidence for effectiveness

This study examines the effectiveness of bibliotherapy for low sexual desire among women, which is the most frequent sexual concern brought to counselors. Forty-five women responded to an advertisement for participation in a study on low sexual desire and were assigned to either the intervention or the wait-list control group. The intervention group completed the Hurlbert Index of Sexual Desire (HISD; Apt & Hurlbert, 1992) and the Female Sexual Function Index (FSFI; R. Rosen et al., 2000), read the self-help book under study in 6 weeks, and completed the measures a second time. The control group completed the same measures 6 weeks apart. Results demonstrated that the intervention group made statistically greater gains over time as compared with the control group on measures of sexual desire (HISD and FSFI Desire subscale), sexual arousal (FSFI Arousal subscale), sexual satisfaction (FSFI Satisfaction subscale), and overall sexual functioning (FSFI Total Score). A subset of participants in the intervention group participated in a 7-week follow-up study, and these participants maintained their gains in sexual desire and overall sexual functioning. Findings have important implications for future research on the efficacy of bibliotherapy generally and for low sexual desire specifically. Results also have vital implications for the treatment of low sexual desire.     

Should social savvy equal good spatial skills? The interaction of social skills with spatial perspective taking

Real-world perspective-taking problems frequently involve interactions among individuals, suggesting a potential social element to this seemingly spatial problem. Previous studies have suggested that the agency of the target in a perspective-taking task might influence reasoning. This hypothesis is tested directly by manipulating whether one takes the perspective of a potential agent or an object. The results were striking: Even though no overall differences in performance were observed with and without agents, performance was differentially associated with social skills. In particular, participants with better social skills were more accurate than less social peers when the target was a potential agent, whereas no such relationship was observed when the target was an object. These results suggest that bringing domain-specific investigations to bear on real-world problems requires understanding how that domain exists in the broader context of interacting skills and biases.     

Repetition blindness reveals differences between the representations of manipulable and nonmanipulable objects

We used repetition blindness to investigate the nature of the representations underlying identification of manipulable objects. Observers named objects presented in rapid serial visual presentation streams containing either manipulable or nonmanipulable objects. In half the streams, 1 object was repeated. Overall accuracy was lower when streams contained 2 different manipulable objects than when they contained only nonmanipulable objects or a single manipulable object. In addition, nonmanipulable objects induced repetition blindness, whereas manipulable objects were associated with a repetition advantage. These findings suggest that motor information plays a direct role in object identification. Manipulable objects are vulnerable to interference from other objects associated with conflicting motor programs, but they show better individuation of repeated objects associated with the same action.
