Selective attention meets spontaneous recognition memory: Evidence for effects at retrieval

Previous research on the effects of Divided Attention on recognition memory have shown consistent impairments during encoding but more variable effects at retrieval. The present study explored whether effects of Selective Attention at retrieval and subsequent testing were parallel to those of Divided Attention. Participants studied a list of pictures and then had a recognition memory test that included both full attention and selective attention (the to be responded to object was overlaid atop a blue outlined object) trials. All participants then completed a second recognition memory test. The results of 2 experiments suggest that subsequent tests consistently show impacts of the status of the ignored stimulus, and that having an initial test changes performance on a later test. The results are discussed in relation to effect of attention on memory more generally as well as spontaneous recognition memory research.     

The relationship between joint attention and theory of mind in neurotypical adults

Joint attention (JA) is hypothesized to have a close relationship with developing theory of mind (ToM) capabilities. We tested the co-occurrence of ToM and JA in social interactions between adults with no reported history of psychiatric illness or neurodevelopmental disorders. Participants engaged in an experimental task that encouraged nonverbal communication, including JA, and also ToM activity. We adapted an in-lab variant of experience sampling methods (Bryant et al., 2013) to measure ToM during JA based on participants’ subjective reports of their thoughts while performing the task. This experiment successfully elicited instances of JA in 17/20 dyads. We compared participants’ thought contents during episodes of JA and non-JA. Our results suggest that, in adults, JA and ToM may occur independently.     

Expectation creates something out of nothing: The role of attention in iconic memory reconsidered

Conscious experience is modulated by attention and expectation, yet is believed to be independent of attention. The experiments on iconic memory (IM) are usually taken as support for this claim. However, a recent experiment demonstrated that when attention is diverted away from the IM letter display subjects fail to see the absence of IM letters. Here we contribute to the ongoing debate by overcoming experimental shortcomings of this previous experiment, by measuring subjective visibility and by testing the effect of the post-cue. We were able to replicate these earlier findings and extend them by demonstrating that subjects who do not realize the absence of letters perceive illusory letters. This result means that there is still phenomenal consciousness, even when attention is diverted. Expectation creates illusory content that overwrites valid IM content. Taken together these findings suggest that the present experimental paradigm is not appropriate to make claims about IM content.     

The effects of arousal reappraisal on stress responses,performance and attention

Background and Objectives: This study examined the effects of arousal reappraisal on cardiovascular responses, demand and resource evaluations, self-confidence, performance and attention under pressurized conditions. A recent study by Moore et al. [2015. Reappraising threat: How to optimize performance under pressure. Journal of Sport and Exercise Psychology, 37(3), 339–343. doi:10.1123/jsep.2014-0186] suggested that arousal reappraisal is beneficial to the promotion of challenge states and leads to improvements in single-trial performance. This study aimed to further the work of Moore and colleagues (2015) by examining the effects of arousal reappraisal on cardiovascular responses, demand and resource evaluations, self-confidence, performance and attention in a multi-trial pressurized performance situation.

Design and Methods: Participants were randomly assigned to either an arousal reappraisal intervention or control condition, and completed a pressurized dart throwing task. The intervention encouraged participants to view their physiological arousal as facilitative rather than debilitative to performance. Measures of cardiovascular reactivity, demand and resource evaluations, self-confidence, task performance and attention were recorded.

Results: The reappraisal group displayed more favorable cardiovascular reactivity and reported higher resource evaluations and higher self-confidence than the control group but no task performance or attention effects were detected.

Conclusion: These findings demonstrate the strength of arousal reappraisal in promoting adaptive stress responses, perceptions of resources and self-confidence.     

A pilot study examining the effects of priming headache illness schema on attentional engagement towards pain relief medication,in those with high and low medication treatment beliefs

Few studies have assessed the underlying theoretical components of the Common Sense Model. Past studies have found, through implicit priming, that coping strategies are embedded within illness schema. Our aim was to evaluate the effect priming ‘headache’ illness schema upon attentional engagement to pain relief medication and to examine the interaction with illness treatment beliefs. Attentional engagement to the pain relief medication (‘Paracetamol’) was assessed using a 2 (primed vs. control) × 2 (strong belief in medication efficacy vs. weak belief in medication efficacy) design. During a grammatical decision task (identifying verbs/non-verbs), participants were randomised to receive a headache prime or a control. Response latency to the target word, ‘Paracetamol’ was the dependent variable. ‘Paracetamol’ treatment beliefs were determined using the brief illness perception questionnaire. Sixty-three participants completed the experiment. There was a significant interaction between illness-primed vs. control and high vs. low treatment efficacy of Paracetamol (p < .001), suggesting an attentional disengagement effect to the coping strategy in illness-primed participants whom held stronger treatment beliefs regarding the efficacy of Paracetamol. In summary, implicit illness schema activation may simultaneously activate embedded coping strategies, which appears to be moderated by specific illness beliefs.     

海洛因戒治者对疼痛线索的选择性注意加工偏向

研究采用点探测范式,以疼痛线索(感觉疼痛词、情感疼痛词和健康灾难词)和中性线索(中性词)为实验材料,考察接受美沙酮维持治疗的海洛因戒治者对疼痛线索的视觉选择性注意偏向。结果表明:海洛因戒治者对疼痛线索的注意偏向具有普遍性,即对感觉疼痛词、情感疼痛词和健康灾难词等三类疼痛线索均存在注意回避偏向,尤其对健康灾难词的注意回避程度最高;海洛因戒治者还对感觉疼痛词和情感疼痛词存在注意脱离易化倾向。本研究对于有针对性的开展注意偏向矫正以干预疼痛,从而辅助美沙酮的治疗效果、维持患者的戒断状态、降低其复吸风险具有重要意义。     

Using spatial vibrotactile cues to direct visual attention in driving scenes

We report two experiments designed to investigate the potential use of vibrotactile warning signals to present spatial information to car drivers. Participants performed an attention-demanding rapid serial visual presentation (RSVP) monitoring task. Meanwhile, whenever they felt a vibrotactile stimulus presented on either their front or back, they had to check the front and the rearview mirror for the rapid approach of a car, and brake or accelerate accordingly. We investigated whether speeded responses to potential emergency driving situations could be facilitated by the presentation of spatially-predictive (80% valid; Experiment 1) or spatially-nonpredictive (50% valid; Experiment 2) vibrotactile cues. Participants responded significantly more rapidly following both spatially-predictive and spatially-nonpredictive vibrotactile cues from the same rather than the opposite direction as the critical driving events. These results highlight the potential utility of vibrotactile warning signals in automobile interface design for directing a driver’s visual attention to time-critical events or information.     

Teachers’ Experience, Attitudes, Feelings and Behavioural Intentions towards Children with Special Educational Needs

This project examined teachers’ attitudes to children with special educational needs. Understanding the implicit and explicit attitudes of teachers is an important precursor to improving teaching practices for children with special needs. Participants (N=77) were pre-service teachers and experienced teachers during in-service training courses. Results showed that behavioural intentions related to explicit rather than implicit attitudes, and that feelings of guilt and anxiety were associated with intentions for negative actions. Profiles of attitudes were substantially similar in terms of personal and teaching experiences. However, attitudes were less positive about children with low social skills and more positive about children with low cognitive skills. Findings have direct application to training teachers of children with special educational needs.
