Can blindness to response-compatible stimuli be observed in the absence of a response?

Blindness to response-compatible stimuli is the finding that targets are identified less accurately when presented during the planning or execution of a congruent response (e.g., right arrow presented during a right keypress) versus an incongruent response (e.g., right arrow presented during a left keypress). Accounts of this effect suggest the planning and execution of a response are critical to its observation. Five experiments investigated whether a blindness effect would be observed in the absence of a planned response. Results suggest that a planned response is not necessary to observe a content-specific blindness effect and that the blindness effect may actually comprise both an action-related component and a symbolic component that is distinct from the action-planning system.     

Symbolic- and response-related contributions to blindness to compatible stimuli

Blindness to compatible stimuli refers to poorer target identification (e.g., right-pointing arrowhead) following compatible stimuli (e.g., right arrows; Stevanovski, Oriet, & Jolic?ur, 2003) and compatible responses (e.g., right key press; Müsseler & Hommel, 1997a and 1997b). To clarify the role of the response in this effect, we examined the impact of adding or removing an overt response. In three experiments, subjects saw an arrow cue (that sometimes required a response) followed by a brief, masked arrowhead, which was reported on all trials. In all experiments, making a response increased the magnitude of the blindness effect. Furthermore, “no response” performance was unaffected by whether subjects had previously responded to the cue. Results favour a two-factor symbolic- plus response-related activation model over a purely symbolic activation model.     

“Caught in the Same Webs”<Emphasis Type="Italic">—</Emphasis>Service Providers’ Insights on Gender-Based and Structural Violence Among Female Temporary Foreign Workers in Canada

Drawing on the experiences of service providers supporting live-in caregivers and migrant agricultural workers in two Canadian provinces (Ontario and Quebec), we explore how structural violence shapes the precarious conditions of female temporary foreign workers. Service providers emphasized how transnational social pressures on women to maintain employment, the captivity involved in women’s employment contracts, the limits on unionization, and women’s isolation and lack of privacy, act together to create an unbalanced relationship between the employer and female worker. In turn, this leads to precarious migration and work conditions that foster a vulnerability to violence and abuse while at the same time limiting access to and delivery of services and social support to female temporary foreign workers. Amid these restrictions, service providers focus on making a difference where they can through initiatives such as human rights education workshops, offering support, understanding Canadian regulation, and empowerment workshops. Greater Canadian national options for permanent residency status could provide a basis for adequate services to temporary foreign workers as part of their universal human rights. Temporary foreign workers contribute to Canadian society, making it encumbant upon the Canadian state to ensure the respect of their universal human rights.     

Interactive activation in visual word recognition: constraints imposed by the joint effects of spatial attention and semantics

Two lexical-decision experiments investigated the effects of semantic priming and stimulus intensity when target location varied and was cued by an abrupt onset. In Experiment 1, the spatial cue was a good predictor of target location, and in Experiment 2 it was not. The results indicate that word recognition processes were postponed until spatial attention was focused on the target and that whether attention further affected word recognition depended on cue validity. The joint effects of cue validity and priming interacted when cue validity was high but were additive when cue validity was low. The joint effects of stimulus intensity and semantic priming also varied according to cue validity (i.e., interactive when high and additive when low). The results are discussed in terms of their implications for visual word recognition, the distinction between exogenous and endogenous spatial attention, and how attention is affected by visual word recognition processes.     

Orienting in space and time: Joint contributions to exogenous spatial cuing effects

We examined whether the time course of exogenous spatial-cuing effects is sensitive to the allocation of attention in time. Expectation for a target within a particular time window following the cue was manipulated by varying the proportion of trials that appeared at each of three stimulus onset asynchronies in both a detection task and a two-alternative forced-choice discrimination task. The time course of spatial-cuing effects was sensitive to the temporal expectation manipulation only in the discrimination task. The results are discussed with reference to the role of attentional set in exogenous spatialcuing paradigms.     

Traumatization of group leaders in their work with displaced persons

Displaced persons are a special, threatened group of people, participants in this war, who were suddenly forced to abandon their homes. The majority of them were, overnight, left without anything they had, some even without their closest family. They all have one thing in common: they have all lost so much. Work with such people is directed toward overcoming their feelings of loss and abandonment and preventing psychical decompensation. Groups of displaced persons temporarily sheltered in the Rijeka region have been observed to be markedly regressed, with increased sensitivity, a low degree of tolerance, great demands on society and strongly expressed projective tendencies. Therapists suffer personal traumatization in working with displaced persons. This paper describes the reactions and feelings of group leaders caused by manifestations of group dynamics in different phases of exile.     

Blinded by headlights.

Target identification is impaired when targets are presented during the planning or execution of a compatible response (e.g., right-pointing arrow during a right keypress) relative to an incompatible response (Müsseler & Hommel, 1997 a, b). Examinations of this blindness to response-compatible stimuli have typically used arrowheads as targets ("<" and ">"). The importance of the target symbol was examined by manipulating subjects' interpretation of that symbol (i.e., ">" interpreted as a right-pointing arrow or as a headlight shining to the left). Targets were presented at varying times during the planning or execution of a response in order to examine the time-course of the effect. Results showed that the interpretation, and not the physical identity, of the target was important for the blindness effect. Although the blindness effect was largest during the planning and execution of a response, it was not always confined to that temporal interval.     

Feature binding and episodic retrieval in blindness for congruent stimuli: evidence from analyses of sequential congruency

Targets are identified more poorly when presented during a congruent cued response than during an incongruent cued response (blindness effect). The authors investigated sequential trial dependencies in the blindness effect. The results show that the size of the blindness effect depends both on the previous cued response-target congruency relationship and on repetition of events from the preceding trial. This finding suggests that cued responses and targets become linked together in a single episodic trace; repeating one of these events from the preceding trial activates the other. Depending on whether the activated representation matches or conflicts with events on the current trial, target identification performance is either facilitated or impaired. Implications for action planning and feature binding are discussed.     

Proactive Coping as a Mediator Between Resources and Outcomes: A Structural Equations Modeling Analysis

Proactive coping is a recent construct in the field of positive psychology. It refers to the efforts aimed at building general forces to facilitate the path toward challenging goals and personal growth. The current study adopted a theoretical model of proactive coping as a mediator of resources with positive and negative outcomes. Our aim was to examine two separate models with satisfaction with life and depression as the proposed outcomes of proactive coping. The proposed models presumed direct relationships between self-efficacy, optimism and social support with life satisfaction or depression, as well as indirect paths through proactive coping. We administered a set of questionnaires that consisted of demographic data, the Proactive Coping Scale, the General Self-efficacy Scale, the Life Orientation Test-Revised, the Perceived Social Support Scale, the Beck Depression Inventory, and the Satisfaction with Life Scale. Data were obtained from a sample of high school graduates (N?=?485, age 17 to 19, 174 males and 311 females). Our analyses confirmed presumed direct and indirect relationships between resources and outcomes. The results showed that the data fit well in the model with life satisfaction as an outcome, while the data did not fit well in the model with depression as an outcome. A subsequent model was formed in which satisfaction with life was used as a full mediator between proactive coping and depression; this model provided a good fit to the data. Theoretical implications, as well as suggestions for future research, are discussed.
