Improving visual spatial working memory in younger and older adults: effects of cross-modal cues

Spatially informative auditory and vibrotactile (cross-modal) cues can facilitate attention but little is known about how similar cues influence visual spatial working memory (WM) across the adult lifespan. We investigated the effects of cues (spatially informative or alerting pre-cues vs. no cues), cue modality (auditory vs. vibrotactile vs. visual), memory array size (four vs. six items), and maintenance delay (900 vs. 1800 ms) on visual spatial location WM recognition accuracy in younger adults (YA) and older adults (OA). We observed a significant interaction between spatially informative pre-cue type, array size, and delay. OA and YA benefitted equally from spatially informative pre-cues, suggesting that attentional orienting prior to WM encoding, regardless of cue modality, is preserved with age. Contrary to predictions, alerting pre-cues generally impaired performance in both age groups, suggesting that maintaining a vigilant state of arousal by facilitating the alerting attention system does not help visual spatial location WM.     

The paradox of the universal triangle: Concepts,language, and prototypes

For over 300 years, the humble triangle has served as the paradigmatic example of the problem of abstraction. How can we have the idea of a general triangle even though every experience with triangles is with specific ones? Classical cognitive science seemed to provide an answer in symbolic representation. With its easily enumerated necessary and sufficient conditions, the triangle would appear to be an ideal candidate for being represented in a symbolic form. I show that it is not. Across a variety of tasks—drawing, speeded recognition, unspeeded visual judgments, and inference—representations of triangles appear to be graded and context dependent. I show that using the category name “triangle” activates a more prototypical representation than using an arguably coextensive cue, “three-sided polygon”. For example, when asked to draw “triangles” people draw more typical triangles than when asked to draw “three-sided polygons”. Altogether, the results support the view that (even formal) concepts have a graded and flexible structure, which takes on a more prototypical and stable form when activated by category labels.     

When leaders are not who they appear: The effects of leader disclosure of a concealable stigma on follower reactions

Two studies examined follower reactions to disclosure of concealable stigma (i.e., transgender identity) by a leader. Using 109 employed participants, Study 1 showed followers rated leaders disclosing a stigma less likable and effective. This effect was both direct and indirect through relational identification with the leader. Using 206 employed participants, Study 2 found when a leader's stigma was involuntarily found out and disclosed later they received lower ratings of likability and effectiveness compared to leaders who voluntarily came out and disclosed earlier. Method (found out vs. came out) and timing of disclosure (later vs. earlier) had direct relationships with ratings of likability and effectiveness and method of disclosure had an indirect relationship with the outcomes via relational identification.     

Princesses,Princes, and Superheroes: Children's Gender Cognitions and Fictional Characters

The goal of the present study was to identify whether children recognize the gender stereotypes prevalent within the increasingly popular princess, prince, and superhero characters. Interviews with 126 children from the northeast region of the Unites States (3–11 years old) indicated that children recognized the gender-typed personality traits of princesses, princes, and superheroes, with older children holding more gender-typed cognitions about the characters. Children's own-schemas (i.e., beliefs that apply to themselves) and superordinate schemas (i.e., include beliefs about others' preferences and behaviors) for the characters were mostly gender typed and congruent. Older children gender-typed princesses as for girls more than younger children, whereas older children considered superheroes to be for boys and girls more than younger children did. Older children also considered the characters to be for them less, potentially reducing the negative implications of exposure to gender-typed messages associated with the characters. Individual differences exist in children's perceptions of these fictional characters, with children's own androgyny being positively correlated with their perceptions of princesses' androgyny levels. Further, girls were more flexible in their stereotyping of princesses, noting they were “for girls and boys” more. The authors discuss the results' practical and theoretical implications.     

Neoliberal Education for Work Versus Liberal Education for Leisure

My concern in this essay is not so much with the invisible work or hidden labor produced by neoliberalism, but rather with what Joseph Pieper describes as an emerging culture of “total work” (Pieper, p. 43). More than the sheer (and increasing) number of hours of work, Pieper diagnoses a transformation in the way we view work. Work (or the necessary tasks of production and consumption) has become the exclusive point of reference for how we see and define ourselves. We are, Pieper feared, increasingly incapable of seeing beyond the working self. The human being (or homo sapien) has become the human worker (or homo faber). Historically, the ideal of leisure offered a counter vision (and its practices a counterbalance) to this tendency. Michael Oakeshott notes that while human beings must attend to the necessities for survival, they are most especially distinguished (from other animals) by their capacity for leisure—by an ability to pursue questions, conversations, and explorations that transcend the realm of production and consumption (Oakeshott 1989). To overlook and exclude leisurely pursuits is to diminish our humanity.     

Co-Rumination Exacerbates Stress Generation among Adolescents with Depressive Symptoms

Through stress generation, individuals’ own thoughts and behaviors can actually lead to increases in their experience of stress. Unfortunately, stress generation is especially common among individuals who are already suffering from elevated depressive symptoms. However, despite the acknowledgement that some individuals with depressive symptoms generate greater stress than others, few studies have identified specific factors that could exacerbate stress generation among individuals with depressive symptoms. The present study examines co-rumination as a factor that might exacerbate stress generation among adolescents with depressive symptoms using a short-term longitudinal design. Considering these processes among adolescents was critical given that many youth experience increases in depressive symptoms at this developmental stage and that co-rumination also becomes more common at adolescence. Participants were 628 adolescents (326 girls; 302 boys) who reported on their depressive symptoms, experiences of stress, and co-rumination with a best friend. Interpersonal stressors (peer and family stress) and non-interpersonal stressors (school and sports stress) were assessed. Consistent with past research, adolescents with depressive symptoms experienced greater interpersonal and non-interpersonal stress over time. Importantly, co-rumination interacted with both depressive symptoms and gender in predicting increases in peer stress. Depressive symptoms predicted the generation of peer stress only for girls who reported high levels of co-rumination with friends. Implications for protecting youth with depressive symptoms against stress generation are discussed.     

Putting It on the Line: Telephone Counseling for Adolescent Smokers

Adolescent smokers need cessation help, but the question of how best to intervene remains unanswered. This article describes the empirically validated protocol of an established, well‐utilized adolescent telephone counseling program for smoking cessation, tailored to adolescent developmental needs and shown to increase clients' 6‐month prolonged abstinence rate significantly. Clinical issues addressed include client assessment, motivation, self‐efficacy, familial and social support, planning, coping, relapse‐sensitive call scheduling, and self‐image. Counselor training considerations are also discussed.     

Contributions of processing ability and knowledge to verbal memory tasks across the adult life-span

This study investigated the relationships of processing capacity and knowledge to memory measures that varied in retrieval difficulty and reliance on verbal knowledge in an adult life-span sample (N = 341). It was hypothesized that processing ability (speed and working memory) would have the strongest relationship to tasks requiring active retrieval and that knowledge (vocabulary ability) would be related to verbal fluency and cued recall, as participants relied upon verbal knowledge to retrieve category items (fluency) or develop associations (cued recall). Measurement and structural equation models were developed for the entire sample and separately for younger (aged 20-54 years, n = 168) and older (aged 55-92 years, n = 173) subgroups. In accordance with the hypotheses, processing ability was found to be most highly related to free recall, with additional significant relationships to cued recall, verbal fluency, and recognition. Knowledge was found to be significantly related only to verbal fluency and to cued recall. Moreover, knowledge was more important for older than for younger adults in mediating variance in cued recall, suggesting that older adults may use age-related increases in knowledge to partially compensate for processing declines when environmental support is available in memory tasks.
