Evidence from a response choice task reveals a selection bias in the attentional cueing paradigm

In a typical attentional cueing paradigm, irrelevant peripheral cues produce early facilitation (fast responses) followed by later inhibition (slow responses) to cued locations. Here we examine whether cues not only influence the speed with which responses are produced, but also impact or bias which location is ultimately selected as requiring a response. Specifically, can cues influence not only the speed with which we respond but also influence the behavior produced? To examine this question, a choice localization task was used in which no targets were presented, and subjects were asked to choose which effector (left hand, right hand) to use in response to a centrally presented tone. Thus, following either a left or right peripheral cue, and then a central tone, subjects were free to respond with either their left or right hand. Early facilitation and later inhibition with this choice procedure were found in both response times and the proportion of responses to the cued and uncued locations. These results suggest that there are processes which initially bias response selection toward cued locations and then subsequently bias response selection away from cued locations.     

AN EVALUATION OF TWO METHODS FOR INCREASING SELF-INITIATED VERBALIZATIONS IN AUTISTIC CHILDREN

Three children with autism and mental retardation were treated for deficits in self-initiated speech. A novel treatment package employing visual cue fading was compared with a graduated time-delay procedure previously shown to be effective for increasing self-initiated language. Both treatments included training multiple self-initiated verbalizations using multiple therapists and settings. Both treatments were efffective, with no differences in measures of acquisition of target phrases, maintenance of behavioral gains, acquisition with additional therapists and settings, and social validity.     

Testing whether gaze cues and arrow cues produce reflexive or volitional shifts of attention

It has been suggested that two types of uninformative central cues produce reflexive orienting: gaze and arrow cues. Using the criterion that voluntary shifts of attention facilitate both response speed and perceptual accuracy, whereas reflexive shifts of attention facilitate only response speed (Prinzmetal, McCool, & Park, 2005), we tested whether these cues produce reflexive or volitional shifts of attention. A cued letter discrimination task was used with both gaze (Experiments 1A and 1B) and arrow (Experiments 2A and 2B) cues, in which participants responded to the identity of the target letter. In the response time (respond speed) tasks, participants were asked to respond as quickly as possible to the target; in the accuracy (perceptual quality) tasks, participants were asked to respond as accurately as possible. For both cue types, compatible cues were found to facilitate response speed but not perceptual accuracy, indicating that both gaze and arrow cues generate reflexive shifts in attention.     

Inhibition of return in single and dual tasks: examining saccadic, keypress, and pointing responses

Two experiments are reported in which inhibition of return (IOR)was examined wit h single-responsetasks (either manual responses alone or saccadic responses alone) and dual-response tasks (simultaneous manual and saccadic responses). The first experiment-using guided limb movements that require considerable spatial information-showed more IOR for saccades than for pointing responses. In addition, saccadic IOR was reduced with concurrent pointing movements, but manual IOR was not affected by concurrent saccades. Importantly, at the time of saccade initiation, the arm movements did not start yet, indicating that the influence on saccade IOR is due to arm-movement preparation. In the second experiment, using localization keypress responses that required only minimal spatial information, greater IOR was again found for saccadic than for manual responses, but no effect of concurrent movements was found. These findings add further support that there is a dissociation between oculomotor and skeletal-motor IOR. Moreover, the results show that the preparation manual responses tend to mediate saccadic behavior-but only when the manual responses require high levels of spatial accuracy-and that the superior colliculus is the likely neural substrate integrating IOR for eye and arm movements.     

Can Becoming My Self Influence My Health?: Exploring the Effects of a Eudaimonic-Enhancement Process on Psychological Indicators of Well-Being and Physical Activity

The current study adopts an intervention approach that begins with the assumption that the quality of a person’s lived experience is at the core of well-being and health behavior change. Specifically, the present study used a well-being enhancement process grounded in eudaimonia to explore the connection among eudaimonia, indicators of psychological well-being (i.e., personal growth, subjective vitality, self-determination, and life engagement), and physical activity. Participants in the intervention group engaged in 8 weekly, group eudaimonic well-being enhancement (the Well-Being Way, WBW) sessions with assessments at Weeks 1, 8, and 12 (follow-up), and were compared to a comparison group that did not participate. A series of 2?×?3 (Group by Time) repeated measures ANOVAs along with follow-up paired comparisons t-tests were conducted to compare the WBW and comparison groups across time. Results indicated that the WBW group exhibited significant increases in two indices of psychological well-being (trait subjective vitality and self-determination) and in their physical activity levels. The comparison group showed no changes in any of the variables. The results of an exploratory regression analysis provided some evidence that WBW participants who experienced the greatest gains in life engagement and trait subjective vitality also exhibited significant increases in level of physical activity. Discussion focuses on the implications of the Well-Being Way approach for the enhancement of positive well-being and future possibilities for eudaimonic-based approaches to health behavior change.     

Racial socialization, racial identity, and Black students' adjustment to college

The purpose of this study was to examine the effects of racial socialization and racial identity on adjustment in Black college students. Self-report questionnaires were administered to 141 Black college students from a predominantly White university and racially diverse college. The findings suggest that racial socialization positively contributes to academic adjustment. An internalized-multicultural identity positively contributed to overall college adjustment, and pre-encounter miseducated racial identity negatively contributed. Internalized Afrocentric racial identity was negatively related to overall college adjustment. Implications for multicultural social scientists and directions for future research are discussed.     

Inhibition of return to social signals of fear

The present study examined whether inhibition of return (IOR) is modulated by the fear relevance of the cue. Experiment 1 found similar magnitude of IOR was produced by neutral and fear faces and luminance matched cues. To allow a more sensitive measure of endogenously directed attention, Experiment 2 removed a central reorienting cue and more precisely measured the time course of IOR. At stimulus onset asynchronies (SOAs) of 500, 1,000 and 1,500 ms, fear face and luminance matched cues resulted in similar IOR. These findings suggest that IOR is triggered by event onsets and disregards event value. Views of IOR as an adaptive "foraging facilitator," whereby attention is guided to promote optimal sampling of important environmental events, are discussed.     

Out of sight,out of mind: Matching bias underlies confirmatory visual search

Confirmation bias has recently been reported in visual search, where observers who were given a perceptual rule to test (e.g. “Is the p on a red circle?”) search stimuli that could confirm the rule stimuli preferentially (Rajsic, Wilson, & Pratt, Journal of Experimental Psychology: Human Perception and Performance, 41(5), 1353–1364, 2015). In this study, we compared the ability of concrete and abstract visual templates to guide attention using the visual confirmation bias. Experiment 1 showed that confirmatory search tendencies do not result from simple low-level priming, as they occurred when color templates were verbally communicated. Experiment 2 showed that confirmation bias did not occur when targets needed to be reported as possessing or not possessing the absence of a feature (i.e., reporting whether a target was on a nonred circle). Experiment 3 showed that confirmatory search also did not occur when search prompts referred to a set of visually heterogenous features (i.e., reporting whether a target on a colorful circle, regardless of the color). Together, these results show that the confirmation bias likely results from a matching heuristic, such that visual codes involved in representing the search goal prioritize stimuli possessing these features.     

Diurnal variation in the Positive Affects

We examined the circadian rhythm of two basic dimensions of mood—Positive Affect (PA) and Negative Affect (NA). Subjects were 196 college students in two studies who completed a mood rating form approximately seven times a day for 1 week. Significant diurnal variation was found to exist in overall Positive Affect, and in four component content areas, but not in Negative Affect. Specifically, all components of PA rose sharply from early morning until noon, remained relatively constant until 9 p.m., and then fell rapidly. The rise and fall of PA were quite robust across subjects, but the apparently static level of PA from noon to 9 p.m. was shown to result from averaging across marked individual differences in the time of peak PA. Various potential sources of these individual differences—“morningness-eveningness,” introversion-extraversion, and neuroticism/dysphoria—were investigated. Neither of the personality variables accounted for the significant variation in diurnal mood patterning, but clearly defined morning and evening types did show different patterns. Possible links between the mood pattern obtained and biologically based circadian rhythms, which have been postulated to be dysregulated in depression and mania, are discussed.     

The effects of competent behavior on interpersonal attraction and task leadership

Past research relating to competence and the status of sex-role stereotypes has produced highly divergent and confusing results, while research into their effects on leadership choices has been scarce. With these issues in mind, the current study varied subject sex, competence, and confederate sex to evaluate their influence on attraction, leadership choice, and sex-role stereotyping on a number of bipolar items. Results revealed that competent womenw ere found to be as attractive as competent men, while incompetent women were found to be more attractive than incompetent men. Leadership remained a masculine trait; women assumed much less responsibility for leadership than did men. Thus, while women may be viewed as being as attractive as men when both are competent, they are not given, nor do they assume equivalent amounts of responsibility for leadership. There was generally a lack of sex-role stereotyping on bipolar items.
