Memory for kinesthetically defined target location: evidence for manual asymmetries

Sixteen right-handed male adults performed a pointing task without vision. The participant's arm was moved passively to one of four targets which was subsequently pointed to following a delay of 1, 2, or 10 s. Our previous research on visual memory for target location showed a rapid decay which was comparable for both hands. The present study of memory for kinesthetic target location found decay for the left hand only. These findings suggest two memory stores for target location information, one visual which decays over time but is accessible to both hands and another based on kinesthetic information which is more stable and limb specific.     

Bandwidth and fidelity on the NEO-Five Factor Inventory: replicability and reliability of Saucier's (1998) item cluster subcomponents

Many users of the NEO-Five Factor Inventory (NEO-FFI; Costa & McCrae, 1992) are unaware that Saucier (1998) developed item cluster subcomponents for each broad domain of the instrument similar to the facets of the Revised NEO Personality Inventory (Costa & McCrae, 1992). In this study, I examined the following: the replicability of the subcomponents in young adult university and middle-aged community samples; whether item keying accounted for additional covariance among items; subcomponent correlations with a measure of socially desirable responding; subcomponent reliabilities; and subcomponent discriminant validity with respect to age-relevant criterion items expected to reflect varying associations with broad and narrow traits. Confirmatory factor analyses revealed that all subcomponents were recoverable across samples and that the addition of method factors representing positive and negative item keying improved model fit. The subcomponents correlated no more with a measure of socially desirable responding than their parent domains and showed good average reliability. Correlations with criterion items suggested that subcomponents may prove useful in specifying which elements of NEO-FFI domains are more or less related to variables of interest. I discuss their use for enhancing the precision of findings obtained with NEO-FFI domain scores.     

Gender Differences in Five Factor Model Personality Traits in an Elderly Cohort: Extension of Robust and Surprising Findings to an Older Generation

In college and adult samples, women score higher then men on the Five Factor Model (FFM) personality traits of Neuroticism and Agreeableness. The present study assessed the extent to which these gender differences held in a sample of 486 older adults, ranging in age from 65-98 (M = 75, SD = 6.5), using the NEO-Five Factor Inventory. Mean and Covariance Structure models testing gender differences at the level of latent traits revealed higher levels of Neuroticism (d = .52) and Agreeableness (d = .35) in older women than older men. The consistency of these findings with prior work in younger samples attests to the stability of gender differentiation on Neuroticism and Agreeableness across the lifespan. Gender differences on these traits should be considered in personality research among older, as well as middle age and younger adults.     

Emotional antecedents and consequences of deliberate self-harm and suicide attempts

Emotional experiences immediately prior to (emotional antecedents) and following (emotional consequences) deliberate self-harm and suicide attempts in female inmates (N = 63) were examined. Anger was the antecedent emotion reported by the largest proportion of individuals who had engaged in deliberate self-harm (45.16%), suicide attempts (40.9%), and ambivalent suicide attempts (30%). Relief and other positive emotional shifts were more common in deliberate self-harm (41.94%) (involving no intent to die) than in suicide attempts or ambivalent suicide attempts, particularly for persons with borderline personality disorder. These findings underscore the utility of discriminating between deliberate self-harm and suicidal behavior and highlight the potential role of anger in triggering such behaviors.     

A Preliminary Examination of the Role of Emotion Differentiation in the Relationship Between Borderline Personality and Urges for Maladaptive Behaviors

Impulsive, maladaptive, and potentially self-damaging behaviors are a hallmark feature of borderline personality (BP) pathology. Difficulties with emotion regulation have been implicated in both BP pathology and maladaptive behaviors. One facet of emotion regulation that may be particularly important in the relation between BP pathology and urges for maladaptive behaviors is emotion differentiation. Over 1 day, 84 participants high (n?=?34) and low (n?=?50) in BP pathology responded to questions regarding state emotions and urges to engage in maladaptive behaviors using handheld computers, in addition to a measure of emotion-related difficulties controlling impulsive behaviors. Results revealed that individuals high in BP pathology reported greater emotion-related impulsivity as well as daily urges to engage in maladaptive behaviors. However, the association between BP group and both baseline emotion-related impulsivity and daily urges for maladaptive behaviors was strongest among individuals who had low levels of positive emotion differentiation. Conversely, negative emotion differentiation did not significantly moderate the relationships between BP group and either emotion-related difficulties controlling impulsive behaviors or state urges for maladaptive behaviors. Limitations to the present study include the reliance upon an analogue sample and the relatively brief monitoring period. Despite limitations, these results suggest that, among individuals with high BP pathology, the ability to differentiate between positive emotions may be a particularly important target in the reduction of maladaptive behaviors.     

An Investigation of Psychology Staffing in Australian Metropolitan Acute Public Hospitals

Psychology is one component of the multidisciplinary services provided to patients in acute public hospitals, with research demonstrating that psychological intervention significantly enhances clinical outcomes for patients across a range of health issues. Despite the increasingly important role that psychologists play in Australian hospitals, there remains a lack of information available about staff levels, discipline structures, and clinical activity for psychological services within acute hospital settings. The most recent Australian data about hospital‐based psychology services was collected 20 years ago. The current study provides updated information from a survey of 15 Australian metropolitan, acute public hospitals: presenting and critically reviewing staffing configurations and models of service delivery. Results suggest that: (a) hospitals employ a highly skilled workforce at a rate of 0.16 full‐time equivalent psychology staff for every 10 hospital beds; (b) psychologists have a viable career pathway within the hospital‐based health sector; (c) role diversity is common, with the primary focus varying as a function of position level; (d) neuropsychology staffing requires urgent attention to address significant delays in access to services; and (e) public hospitals actively contribute to current and future workforce development through supervision, research, and training. The implications of these results for the future of psychological services in Australian healthcare are discussed.     

Memory load as a cognitive antidote to performance decrements in data entry

In two experiments, subjects trained in data entry, typing one 4-digit number at a time. At training, subjects either typed the numbers immediately after they appeared (immediate) or typed the previous number from memory while viewing the next number (delayed). In Experiment 2 stimulus presentation time was limited and either nothing or a space (gap) was inserted between the second and third digits. In both experiments after training, all subjects completed a test with no gap and typed numbers immediately. Training with a memory load improved speed across training blocks (Experiment 1) and eliminated the decline in accuracy across training blocks (Experiment 2), thus serving as a cognitive antidote to performance decrements. An analysis of each keystroke revealed different underlying processes and strategies for the two training conditions, including when encoding took place. Chunking (in which the first and last two digits are treated separately) was more evident in the immediate than in the delayed condition and was exaggerated with a gap, even at test when there was no gap. These results suggest that such two-digit chunking is due to stimulus encoding and motor planning processes as well as memory, and those processes transferred from training to testing.
