Heart-beat perception, panic/somatic symptoms and anxiety sensitivity in children

There is considerable evidence implicating heart-beat perception (HBP) accuracy and anxiety sensitivity (AS) in the development of panic in adults. However, to date there have been no studies exploring the association between HBP, AS and childhood panic/somatic symptoms. Seventy-nine children aged 8 to 11 years completed a mental tracking paradigm (Psychophysiology 18 (1981) 483) to assess HBP, the Children's Anxiety Sensitivity Index (J Clin Chil Psychol 20 (1991) 162) and the Screen for Childhood Anxiety Related Emotional Disorders (J Am Acad Child Adoles Psych 38 (1999) 1230). Those with good HBP (n = 7, 9%) had significantly higher panic/somatic symptoms (t = -1.71, P < 0.05), and AS (t = -2.16, P < 0.02) than those with poor HBP. There were no effects of age, sex or BMI on HBP. Those with high levels of panic/somatic symptoms were seven times more likely to have good HBP and had AS scores 1 S.D. higher than the remainder of the sample. Multivariate analyses revealed that these two phenotypes had independent associations with high panic/somatic symptoms. These results extend the literature on HBP and panic and suggest that in children, as in adults, increased panic/somatic symptoms are associated with enhanced ability to perceive internal physiological cues, and fear of such sensations.     

Perceiving unfairness in the family: cause or consequence of marital distress?

This research tests a model suggesting that marital distress leads individuals to scrutinize what is given and received in the relationship. This scrutiny elicits perceptions of unfairness that maintain or exacerbate marital distress. In a 3-panel longitudinal study tracking married couples across the transition to parenthood, both wives' and husbands' reports of marital conflict and wives' marital dissatisfaction at Time 1 positively predicted perceived unfairness of the allocation of household tasks at Time 2, controlling for earlier perceptions of unfairness. In addition, there was evidence of perceived unfairness of division of labor at Time 2 predicting marital conflict and marital dissatisfaction for wives at Time 3, controlling for earlier conflict and dissatisfaction. This model of relationship distress and perceptions of unfairness is contrasted with prior interpretations of links between perceived injustice and distress in relationships.     

The Relationship Between Nonsuicidal Self‐Injury and Suicidal Ideation

This correlational study was conducted with 403 undergraduate college students from 2 universities. The authors used path analysis and bootstrap regression to analyze the relationships between variables. Locus of control and family connectedness related to current nonsuicidal self‐injury (NSSI) engagement. However, when entered into the same regression, the variables current NSSI engagement and current NSSI number of methods used mediated all other relationships with suicidal ideation. Implications to current theories and clinical practice are provided.     

Feeling of knowing and duration of unsuccessful memory search

Five experiments examined the impact of feeling of knowing on decisions to continue or to terminate the search of memory in question answering. First, two pairs of experiments respectively scrutinized knowledge about (1) ordinary facts and (2) national capitals. The first experiment of each pair extracted normative data: The participants indicated whether they had probably once known the answer to a question (once-knew-it scale), supplied the answer if they knew it, and either judged the likelihood of their recognizing the answer or made other pertinent metacognitive judgments. In these norming experiments, recognition ratings were highly correlated with once-knew-it responses, and both measures were highly predictive of performance. Thisindicated that both measures reflect feeling of knowing judgments. In the second experiment of each pair, different participants were timed as they indicated whether they knew the answer to the same questions. Responselatencies for responding "don't know" were strongly positively correlated with the once-knew-it judgments made by the norming participants. This relationship was corroborated by Experiment 5, which compared the crucial measures within participants. These outcomes suggest that, in this context, feeling of knowing judgments are predictive of how long people will search memory for requested information.     

Cerebellar-Subcortical-Cortical Systems as Modulators of Cognitive Functions

Higher order pattern structure influences auditory representational momentum

Representational momentum refers to the phenomenon that observers tend to incorrectly remember an event undergoing real or implied motion as shifted beyond its actual final position. This has been demonstrated in both visual and auditory domains. In 5 pitch discrimination experiments, listeners heard tone sequences that implied either linear, periodic, or null motions in pitch space. Their task was to judge whether the pitch of a probe tone following each sequence was the same or different from the final sequence tone. Results suggested that listeners made errors consistent with extrapolation of coherent pitch patterns (linear, periodic) but not with incoherent (null) ones. Hypotheses associated with internalized physical principles and pattern-based expectations are discussed.     

Recollection and familiarity in recognition memory: adult age differences and neuropsychological test correlates

Dual process theories account for age-related changes in memory by proposing that old age is associated with deficits in recollection together with invariance in familiarity. The authors evaluated this proposal in recognition by examining recollection and familiarity estimates in young and older adults across 3 process estimation methods: inclusion/exclusion, remember/know, and receiver operating characteristics (ROC). Consistent with a previous literature review (Light, Prull, LaVoie, & Healy, 2000), the authors found age invariance in familiarity when process estimates were derived from the inclusion/exclusion method, but the authors found age differences favoring the young when familiarity estimates were derived from the remember/know and ROC methods. Recollection estimates were lower for older adults in all 3 methods. Recollection and familiarity had variable relationships with frontal- and temporal-lobe measures of neuropsychological functioning in older adults, depending on which method was used to generate process estimates. These data suggest that although recollection deficits appear to be the rule in aging, not all estimates of familiarity show age invariance.
