The profile of attention differs between locations orthogonal to and in line with reach direction

People make movements in a variety of directions when interacting with the world around them. It has been well documented that attention shifts to the goal of an upcoming movement, whether the movement is a saccade or a reach. However, recent evidence suggests that the direction of a movement may influence the spatial spread of attention (Stewart & Ma-Wyatt, 2015, Journal of Vision, 15(5), 10). We investigated whether the spatiotemporal profile of attention differs depending on where that location is situated relative to the direction of movement, and if this pattern is consistent across different movement effectors. We compared attentional facilitation at locations in line with or orthogonal to the movement, for reach-only, reach-plus-saccade, and saccade-only conditions. Results show that the spatiotemporal profile of attention differs across different movement combinations, and is also different at target locations orthogonal to and in line with the movement direction. Specifically, when a reach alone was made, there was a general decrease in attention at all locations during the movement and a general increase in attention at all locations with a saccade only. However, the concurrent reach and saccade condition showed a premovement attentional facilitation at locations orthogonal to movement direction, but not those in line with the movement direction. These results suggest attentional guidance may be more important at differing time points, depending on the type of movement.     

The influence of only on syntactic processing of long relative clause sentences

We report an eye movement experiment investigating the influence of the focus operator only on syntactic processing of long relative clause sentences. Paterson, Liversedge, and Underwood (1999) found that readers were garden pathed by short reduced relative clause sentences containing the focus operator only . They argued that due to thematic differences between short and long relative clause sentences, garden path effect might not occur when long reduced relative clause sentences are read. Eye-tracking data show that garden path effects found during initial processing of the disambiguating verb of long reduced sentences without only were absent or delayed in the case of counterparts with only . We discuss our results in terms of current theories of sentence processing.     

Visual line bisection in sinistrals and dextrals as a function of hemispace, hand, and scan direction

Visual line bisection was investigated in 26 sinistral and 24 dextral subjects as a function of hemispace, hand and scan direction. An ANOVA revealed significant main effects for hand preference, due to the mean bisection errors of dextral subjects being significantly leftward of those of sinistral subjects; for hand, due to the bisection errors of the left hand being significantly to the left of the right hand; and for scan, due to the bisection errors following a left scan being significantly to the left of a right scan. One significant interaction was found, that between hand and direction of scan, due to a significant difference between left and right hands following a scan from the left but not following a scan from the right. For dextral subjects the leftward bisection errors of the left and right hands following a scan from the left, but not for a scan from the right, differed significantly from the midpoint. For sinistral subjects the leftward bisection errors following a scan from the left and rightward bisection errors following a scan from the right differed significantly from the midpoint for the left hand but not for the right hand. No significant main effect or interactions for hemispace were found. This confirms that both sinistral and dextral subjects display pseudoneglect when using their preferred hand and scanning from the left. However, sinistrals, but not dextrals, will display reversed pseudoneglect when using their preferred hand and adopting a scan direction from the right. These results are discussed in terms of the interaction between three factors, whose influence can jointly and severally produce misbisections, hemispheric specialisation for visuospatial function, hemispheric activation for a manual response, and the allocation of visual attention.     

BIS/BAS responses to emotional cues: Self report, autonomic measure and alpha band modulation

The study explored the effect of the subjective evaluation and of BIS/BAS (Behavioral Inhibition and Activation System) differences on psychophysiological and brain oscillation measures, in response to pleasant/unpleasant and high/low arousing stimuli. Skin conductance response, heart rate, and electromyography, and alpha frequency band, were registered, during viewing IAPS figures. Both BIS and BAS measures were significant in modulating behavioral, autonomic and brain responses, with a clear dichotomy BAS-appetitive/positive BIS-withdrawal/negative sensitivity. Withdrawal (BIS) and appetitive (BAS) behavior showed opposite patterns of responses by the subjects within the frontal cortical site more than other sites. In addition, a specific frontal lateralization effect was found as a function of BIS (more right-side activation for negative cues) and BAS (more left-side activation for positive cues). Moreover, autonomic variables and frequency band were found to be effected by arousal rating per se, with an increased response to high arousal in comparison with low arousal and neutral stimuli. The effects of subjective evaluation and individual differences were discussed in the light of the coping activity of emotion comprehension.     

The effects of social influence on children's memory reports: the omission and commission error asymmetry

Children in two age groups (7 vs. 12 yrs, N= 174) individually interacted with a stranger and were later interviewed about this event. Right before the interview, each child encountered the stranger once again and he engaged in a conversation where he either suggested that a (central or peripheral) detail originally present in the event had actually not been there or that an originally non-present (central or peripheral) detail had in fact been there. It was hypothesized that the two types of misinformation would result in omission and commission errors respectively. The results showed that the social influence resulted in an asymmetric effect (i.e., more commission than omission errors). Importantly, we also found that the children made more errors with respect to the peripheral detail (a suitcase), compared to the central detail (a passenger). Younger children did not make more errors (neither omission nor commission errors) than older children.     

A Systematic Review: Non‐Suicidal Self‐injury in Australia and New Zealand's Indigenous Populations

Objective

To undertake a systematic review of non‐suicidal self‐injury (NSSI) prevalence, patterns, functions, and behavioural correlates for the Indigenous populations of Australia (Aboriginal and Torres Strait Islanders) and New Zealand (NZ; Maori).

Method

We searched the following electronic databases: PubMed, MedLine, Scopus, Web of Science, ScienceDirect, PsycInfo, and PsycArticles, CINAHL, and the Informit Health and Indigenous Peoples collections. Studies were included for review if they were published within the last 25 years and reported on NSSI in Australia and NZ's Indigenous populations.

Results

Seven studies were included, six of which came from Australia. The prevalence of NSSI in Australia ranged from 0.9% up to 22.50%; statistics varied by the different samples, types of prevalence, and relationship to alcohol. Several studies found that Aboriginal and Torres Strait Islander peoples had higher rates of NSSI than other Australians, but that this was not significantly higher. Two studies indicated that NSSI was linked to alcohol use, incarceration, and a younger age. The one NZ study was of injury and not specifically NSSI.

Conclusions

Findings are limited due to a small pool of literature. Cultural variations in NSSI presentation should be considered when working with Indigenous populations. Further research is required to help determine what cultural variations may exist.     

Infants perceive human point-light displays as solid forms

While five-month-old infants show orientation-specific sensitivity to changes in the motion and occlusion patterns of human point-light displays, it is not known whether infants are capable of binding a human representation to these displays. Furthermore, it has been suggested that infants do not encode the same physical properties for humans and material objects. To explore these issues we tested whether infants would selectively apply the principle of solidity to upright human displays. In the first experiment infants aged six and nine months were repeatedly shown a human point-light display walking across a computer screen up to 10 times or until habituated. Next, they were repeatedly shown the walking display passing behind an in-depth representation of a table, and finally they were shown the human display appearing to pass through the table top in violation of the solidity of the hidden human form. Both six- and nine-month-old infants showed significantly greater recovery of attention to this final phase. This suggests that infants are able to bind a solid vertical form to human motion. In two further control experiments we presented displays that contained similar patterns of motion but were not perceived by adults as human. Six- and nine-month-old infants did not show recovery of attention when a scrambled display or an inverted human display passed through the table. Thus, the binding of a solid human form to a display in only seems to occur for upright human motion. The paper considers the implications of these findings in relation to theories of infants' developing conceptions of objects, humans and animals.     

Description and First Steps Toward the Empirical Validation of the Plan Formulation Method for Couples

The aim of this paper is to empirically assess the reliability of the plan formulation method for couples, a procedure for formulating the case, planning, and monitoring the couple therapies according to control-mastery theory. We hypothesized that when couples are looking for couple therapy, they have an unconscious couple’s plan for the therapy, which includes the couple’s goals; the pathogenic beliefs that the partners want to disprove; the traumas from which these beliefs originated and that the partners want to master; the vicious relational circles that make the couple suffer and that the couple wants to break; the virtuous relational circles that are expressions of the couple’s resources and that the couple wants to fuel; and the relational insights that may help the couple get better. Our study involved 15 couples treated by four experienced therapists. Four raters independently formulated each couple’s plan based on the first three sessions following a standard procedure, and we calculated the intraclass correlation for pooled judges’ ratings. For a subsample of three couples—who before and after treatment had completed the dyadic adjustment scale (DAS) and the outcome questionnaire-45.2 (OQ-45.2)—the compatibility of the therapists’ interventions with the couples’ and partners’ plans was assessed. The relationship between the ratings of compatibility, DAS and OQ-45.2, was assessed. The results showed excellent interjudge reliability for each couple’s plan formulation (average ICC?=?0.82), attesting to the validity of the procedure; and preliminary data on the therapeutic process suggested that therapists’ interventions compatible with couple’s plans could help partners achieve good outcomes.
