Context cue focality influences strategic prospective memory monitoring

Monitoring the environment for the occurrence of prospective memory (PM) targets is a resource-demanding process that produces cost (e.g., slower responding) to ongoing activities. However, research suggests that individuals are able to monitor strategically by using contextual cues to reduce monitoring in contexts in which PM targets are not expected to occur. In the current study, we investigated the processes supporting context identification (i.e., determining whether or not the context is appropriate for monitoring) by testing the context cue focality hypothesis. This hypothesis predicts that the ability to monitor strategically depends on whether the ongoing task orients attention to the contextual cues that are available to guide monitoring. In Experiment 1, participants performed an ongoing lexical decision task and were told that PM targets (TOR syllable) would only occur in word trials (focal context cue condition) or in items starting with consonants (nonfocal context cue condition). In Experiment 2, participants performed an ongoing first letter judgment (consonant/vowel) task and were told that PM targets would only occur in items starting with consonants (focal context cue condition) or in word trials (nonfocal context cue condition). Consistent with the context cue focality hypothesis, strategic monitoring was only observed during focal context cue conditions in which the type of ongoing task processing automatically oriented attention to the relevant features of the contextual cue. These findings suggest that strategic monitoring is dependent on limited-capacity processing resources and may be relatively limited when the attentional demands of context identification are sufficiently high.     

Responses of Comparable White and Negro Adults to the Rorschach Test

Five groups of 20 Ss each, ranging from seven years to college age, were asked to solve a series of problems involving change-making and coin equivalences. Results indicated that the number of Ss able to make change without the use of written calculations increased as a consequence of chronological age, with the greatest increase occurring between 11 and 13 years of age. In addition, it was found that although children at all levels knew the various coin equivalences, younger children used primarily dimes and pennies in making change, whereas older children used all of the coins available. This was interpreted to mean that coin equivalences are probably learned as specific stimulus-response pairs, and that in making change younger children use untransformed base 10 units, such as pennies and dimes, largely because the computational demands placed by change-making operations force them to minimize the number of noncomputational transformations used.     

Medial auditory thalamic input to the lateral pontine nuclei is necessary for auditory eyeblink conditioning

Auditory and visual conditioned stimulus (CS) pathways for eyeblink conditioning were investigated with reversible inactivation of the medial (MPN) or lateral (LPN) pontine nuclei. In Experiment 1, Long-Evans rats were given three phases of eyeblink conditioning. Phase 1 consisted of three training sessions with electrical stimulation of the medial auditory thalamic nuclei (MATN) paired with a periorbital shock unconditioned stimulus (US). An additional session was given with a muscimol (0.5 μL, 10 mM) or saline infusion targeting the LPN followed by a recovery session with no infusions. The same training and testing sequence was then repeated with either a tone or light CS in phases 2 and 3 (counterbalanced). Experiment 2 consisted of the same training as Experiment 1 except that muscimol or saline was infused in the MPN during the retention tests. Muscimol infusions targeting the LPN severely impaired retention of eyeblink conditioned responses (CRs) to the MATN stimulation and tone CSs but only partially reduced CR percentage to the light CS. Muscimol infusions that targeted the MPN had a larger effect on CR retention to the light CS relative to MATN stimulation or tone CSs. The results provide evidence that the auditory CS pathway necessary for delay eyeblink conditioning includes the MATN-LPN projection and the visual CS pathway includes the MPN.

Gaze-contingent displays: a review.

Gaze-contingent displays (GCDs) attempt to balance the amount of information displayed against the visual information processing capacity of the observer through real-time eye movement sensing. Based on the assumed knowledge of the instantaneous location of the observer's focus of attention, GCD content can be "tuned" through several display processing means. Screen-based displays alter pixel level information generally matching the resolvability of the human retina in an effort to maximize bandwidth. Model-based displays alter geometric-level primitives along similar goals. Attentive user interfaces (AUIs) manage object- level entities (e.g., windows, applications) depending on the assumed attentive state of the observer. Such real-time display manipulation is generally achieved through non-contact, unobtrusive tracking of the observer's eye movements. This paper briefly reviews past and present display techniques as well as emerging graphics and eye tracking technology for GCD development.     

Adjustment of Siblings of Children with Mental Health Problems: Behaviour, Self-Concept, Quality of Life and Family Functioning

This study examined the adjustment of siblings of children with mental health problems. The participants had brothers or sisters receiving treatment at a Child and Adolescent Mental Health Service within the Hunter New England Health Service, New South Wales, Australia. Seventy-five siblings completed questionnaires on their self-concept, quality of life and family functioning. Their carers completed questionnaires on the sibling’s behaviours, family demographics and family functioning. The diagnosis and severity of disability of index children were attained from the treating clinician. The study revealed the siblings had significantly higher rates of psychopathology, poorer quality of life and lived in more dysfunctional families than normally developing children. Regression modelling predicted variables related to the three main behaviour scales of the Child Behaviour Checklist (CBCL). Family functioning, family communication and the extreme ends of family cohesion and balance, were the most significant contributors to regression model. The sibling self-concept domains of global self-worth, athletic competence and behavioural conduct, contributed to the model. Additionally, a smaller family size was associated with more internalising behaviour disorders in the siblings. The diagnosis and severity of mental health problem of the index child and other family demographic factors did not impact on the sibling’s behavioural functioning. This study highlights that siblings of children with mental health difficulties are a group vulnerable to adjustment difficulties regardless of the index child’s diagnosis or the severity of impairment. Overall, family functioning had a greater impact on the siblings than other factors.     

Altered stress responses in children exposed to early adversity: a systematic review of salivary cortisol studies

Pathological stress responses are implicated in numerous disorders. Hypothalamic-pituitary-adrenal axis function is influenced by gene-environment interaction, with early-life environmental adversity having long-lasting effects. We examine the evidence that, in humans, these effects are apparent from infancy. We systematically reviewed published findings on cortisol response to a stressor, in 0-5-year-olds already exposed to adversity. Adversity was defined as a negative environmental influence present post-conception. We searched Ovid MEDLINE (1950-May 2010), EMBASE (1980-May 2010) and PsychINFO (1806-May 2010). We included peer-reviewed, English language studies that analysed salivary cortisol before and after a standardised stressor. We identified 30 studies, of which 27 reported a significant effect of adversity on the cortisol response to stress. Six of these demonstrated an effect of prenatal substance exposure. Thirteen studies found that psychosocial adversity increased cortisol reactivity. Three studies reported that cortisol reactivity could be normalised by intervention programmes. The studies were heterogeneous, both in nature of adversity studied and in stressor used, precluding meta-analysis and assessment of publication bias. Our review presents evidence that adversity disrupts the stress response from an early age. Longitudinal studies are required to determine whether effects persist, alter with time, or are reversible with intervention.     

Honoring accounts for sexual harassment: A factorial survey analysis

This study analyzes a factorial survey, incorporating vignettes about student-to-student sexual harassment, completed by undergraduates at a small liberal arts college. As in previous studies, perceived seriousness levels for such incidents are shown to depend primarily on the perpetrator's behavior. However, perceived seriousness also depends strongly on the accounts offered by the perpetrator for his behavior and to a lesser extent on verbal reactions of the female victim. Furthermore, some types of accounts reduce the perceived seriousness of the behavior, while others increase it. Male and female respondents differ in their overall means, but do not differ significantly in the factors that influence perceived seriousness. Some implications of these results for the study of sexual harassment and of accounts are noted.
