Canceling out both the real and the spectral lines

Neglect patients typically show motor perseveration while canceling targets on the ipsilesional side. This behavior can be influenced by the presence vs. absence of targets on the (neglected) contralesional side (). As alternative explanations, the authors proposed (i) directional hypokinesia--the patient cannot perform reaching movements towards detected left-sided targets, and thus carries on canceling on the right side, and (ii) allochiria--the patient misperceives left-sided targets as located on the right side, and cancels them there. We report here data from a patient (EZ) that might confirm the second hypothesis. EZ was presented with 19 displays in which the number and position of cancellation targets on both sides were varied systematically. EZ showed motor perseveration while canceling, but this tendency did not vary across conditions. Interestingly though, EZ also drew cancellation marks in the empty space between the ipsilesional targets, and this phenomenon was significantly more intense when there were more targets on the neglected side. As EZ's comments suggested, such a behavior might reflect the attempt to cancel out delusional targets. Our speculation is that those objects were generated by allochiria.     

Attentional focus on supra-postural tasks affects postural control

We examined whether the attentional focus adopted on a supra-postural task has an influence on postural control. Similar to Riley, Stoffregen, Grocki, and Turvey (Human Movement Science 18 (1999) 795), participants were instructed to stand still while lightly touching a loosely hanging sheet with their fingertips. However, instructions varied slightly under two conditions: Participants were either asked to minimize movements of the finger (internal focus) or to minimize movements of the sheet (external focus). In contrast to Riley et al.'s findings, both touch conditions resulted in increased postural sway, compared to a baseline condition (no touch). However, in line with previous findings (e.g., Wulf, McNevin, & Shea, Quarterly Journal of Experimental Psychology 54A (2001) 1143), frequency of responding (fast Fourier transformation) was greater under the external focus condition, compared to both internal focus and baseline conditions. The findings indicate improved static balance responses under external focus conditions and compromised static balance response under internal focus conditions.     

Self-regulation of goal setting: turning free fantasies about the future into binding goals

Fantasy realization theory states that when people contrast their fantasies about a desired future with reflections on present reality, a necessity to act is induced that leads to the activation and use of relevant expectations. Strong goal commitment arises in light of favorable expectations, and weak goal commitment arises in light of unfavorable expectations. To the contrary, when people only fantasize about a desired future or only reflect on present reality, expectancy-independent moderate goal commitment emerges. Four experiments pertaining to various life domains supported these hypotheses. Strength of goal commitment was assessed in cognitive (e.g., making plans), affective (e.g., felt attachment), and behavioral terms (e.g., effort expenditure, quality of performance). Implications for theories on goal setting and goal striving are discussed.     

Resource diary: A positive writing intervention for promoting well-being and preventing depression in adolescence

Depression in adolescence is a widespread problem and leads to extensive psychosocial impairments. For these reason, a resource diary has been developed as a four-week positive writing intervention. The aims of this intervention were to enhance well-being, to promote emotion regulation and resource realization, as well as to prevent symptoms of depression in adolescence. Seventy-seven students of 8th form were randomized either to a positive writing group (n = 38) or to a neutral writing group (n = 39). At the post-test, the positive writing group showed a lower dysphoric mood, fewer worries and less rumination in comparison with the neutral writing group. No effects on resource realization were detected. This study provides the first evidence of the beneficial effects of positive writing on indicators of well-being and depressive symptoms. In conclusion, the resource diary represents an economical intervention for preventing depression in adolescence.     

Examining explanatory mechanisms of positive and expressive writing: Towards a resource-oriented perspective

This study tested the hypothesis that benefits of positive and expressive writing accrue when the intervention matches or activates the participant’s personal resources. Students were randomly assigned to keep a newly developed resource diary (RD, n = 114), which asked the participants to write about positive experiences and personal resources, or an expressive writing diary (ED, n = 114), which asked the participants to engage with negative emotional experiences, at home on three consecutive days per week for four weeks. Participants keeping the RD perceived significantly more social support and reported a significantly better mood at post-test than participants keeping the ED. Compared to a control group (n = 81) treatment effects of both writing interventions were higher for participants with lower pre-test values of well-being and brooding as well as for participants who wrote in an ‘atmosphere of activated resources.’ It is suggested that research should move away from testing deficit-compensating hypotheses towards a stronger resource orientation.     

The power of prospection: mental contrasting and behavior change

People often immerse themselves in dreams and fantasies about a desired future. Though such future fantasies are pleasant, they do not necessarily lead to the effort required to attain the desired future. Indeed, the more positively people fantasize about their desired futures, the less effort they invest and the less successful they are in realizing these futures. However, when fantasies about a desired future are complemented with a clear sense of reality, people find the direction and energy needed to realize their fantasies. We review Fantasy Realization Theory, which explicates these ideas and led to the discovery of mental contrasting future and reality, a self‐regulation strategy of behavior change. Mental contrasting helps people figure out what they really want and wisely select, commit to, and actively pursue prioritized wishes while constructively dealing with setbacks. It helps them live a rewarding life through work, play, health, and relationships.     

Nonnaïveté among Amazon Mechanical Turk workers: Consequences and solutions for behavioral researchers

Crowdsourcing services—particularly Amazon Mechanical Turk—have made it easy for behavioral scientists to recruit research participants. However, researchers have overlooked crucial differences between crowdsourcing and traditional recruitment methods that provide unique opportunities and challenges. We show that crowdsourced workers are likely to participate across multiple related experiments and that researchers are overzealous in the exclusion of research participants. We describe how both of these problems can be avoided using advanced interface features that also allow prescreening and longitudinal data collection. Using these techniques can minimize the effects of previously ignored drawbacks and expand the scope of crowdsourcing as a tool for psychological research.     

Language Mapping with Verbs and Sentences in Awake Surgery: A Review

Intraoperative language mapping in awake surgery is typically conducted by asking the patient to produce automatic speech and to name objects. These tasks might not map language with sufficient accuracy, as some linguistic processes can only be triggered by tasks that use verbs and sentences. Verb and sentence processing tasks are currently used during surgery, albeit sparsely. Medline, PubMed, and Web of Science records were searched to retrieve studies focused on language mapping with verbs/sentences in awake surgery. We review the tasks reported in the published literature, spell out the language processes assessed by each task, list the cortical and subcortical regions whose stimulation inhibited language processing, and consider the types of errors elicited by stimulation in each region. We argue that using verb tasks allows a more thorough evaluation of language functions. We also argue that verb tasks are preferable to object naming tasks in the case of frontal lesions, as lesion and neuroimaging data demonstrate that these regions play a critical role in verb and sentence processing. We discuss the clinical value of these tasks and the current limitations of the procedure, and provide some guidelines for their development. Future research should aim toward a differentiated approach to language mapping – one that includes the administration of standardized and customizable tests and the use of longitudinal neurocognitive follow-up studies. Further work will allow researchers and clinicians to understand brain and language correlates and to improve the current surgical practice.
