Event-related potential data acquisition on the Apple II+/IIe

Event-related potential (ERP) research is a valuable technique for understanding neural mechanisms underlying cognition. With few exceptions, this research has used minicomputer-based data-acquisition systems, thus limiting ERP research to labs with large computers. The hardware and software presented here allow the Apple II+ or Apple IIe microcomputers to present stimuli and collect data from as many as three electrode sites. A fourth electrode site may be used to monitor eyeblinks and allows the exclusion of those trials in which an eyeblink occurs. After the data are collected and averaged, they are stored by subject, task, and electrode on disk where they subsequently may be displayed, analyzed, or downloaded to a mainframe computer.     

Measuring the Creative Process: A Psychometric Examination of Creative Ideation and Grit

Within the investment theory of creativity (Sternberg & Lubart, 1996), creativity is defined as a 2-part process of buying low by investing in unusual ideas and then selling high by convincing others of the value or usefulness of these new ideas. This process requires both creative ideation and perseverance. The purpose of this research was to examine the psychometric properties of instrumentation proposed to assess the 2 underlying constructs in this definition: the creative ideational behavior required to buy low and the persevering behavior required to sell high. In particular, psychometric properties of a creativity ideation measure, the Runco Ideational Behavior Scale (RIBS Scale: Runco, Plucker, & Lim, 2001) and a perseverance measure, the Grit Scale (Duckworth, Peterson, Matthews, & Kelly, 2007) were examined in this study. Two samples of undergraduate students (N = 187; N = 817) completed a survey including these two scales and demographic information. Factor analyses were performed on the RIBS and Grit Scales. The RIBS Scale was found to have a 2-factor structure and 2 proposed new subscales. The Grit Scale’s previously reported 2-factor structure was confirmed.     

Can Prayer Increase Charitable Giving? Examining the Effects of Intercessory Prayer,Moral Intuitions,and Theological Orientation on Generous Behavior

This study was designed to investigate the effects of intercessory prayer, moral intuitions, God concept, and theological orientation on generous behavior in the form of charitable giving. Christian participants (N = 313) were assigned to engage in either intercessory prayer or a secular reflection over a 2-week period on the hardships faced by either Christians (religious ingroup) or Muslims (religious outgroup) in Myanmar/Burma being persecuted by the Buddhist majority. Contrary to hypotheses and previous research, multiple regression analyses revealed that the prayer condition was associated with less monetary generosity than a nonreligious control condition. Ingroup versus outgroup status of the target of prayer/reflections was not a significant predictor of charitable giving. Moral intuitions related to the harm/care and fairness/reciprocity foundations as well as traditional God concept moderated the effects of prayer.     

Adherence to HAART: perspectives from clients in treatment support programs

The development of highly active antiretroviral therapy (HAART) has resulted in dramatic decreases in morbidity and mortality for HIV-infected individuals. Because the long-term efficacy of HAART is dependent on near perfect adherence, many providers offer services to support adherence, including education, regimen review, counseling, and reminder tools. Little is known regarding the utilization or efficacy of these services. In this paper, we report on data collected during 32 open-ended interviews conducted with individuals receiving services through the New York State Treatment Adherence Demonstration Project. Participants in the project reported deriving benefits from a broad range of project activities. Educational efforts helped clients to recognize HIV as a manageable, rather than terminal, illness. Information and tools focused on specific regimens provided clients with concrete knowledge and skills. Effective communication with medical providers and pharmacists was facilitated by adherence staff who proactively advocated for client needs. Program-based social support was particularly valuable for many participants, helping them to retain needed motivation and strength. Educational, practical, and supportive services were all considered valuable to clients participating in adherence support programs. A mix of services may best meet the range of needs found among persons taking HAART.     

Unitary vs multiple semantics: PET studies of word and picture processing

In this paper we examine a central issue in cognitive neuroscience: are there separate conceptual representations associated with different input modalities (e.g., Paivio, 1971, 1986; Warrington & Shallice, 1984) or do inputs from different modalities converge on to the same set of representations (e.g., Caramazza, Hillis, Rapp, & Romani, 1990; Lambon Ralph, Graham, Patterson, & Hodges, 1999; Rapp, Hillis, & Caramazza, 1993)? We present an analysis of four PET studies (three semantic categorisation tasks and one lexical decision task), two of which employ words as stimuli and two of which employ pictures. Using conjunction analyses, we found robust semantic activation, common to both input modalities in anterior and medial aspects of the left fusiform gyrus, left parahippocampal and perirhinal cortices, and left inferior frontal gyrus (BA 47). There were modality-specific activations in both temporal poles (words) and occipitotemporal cortices (pictures). We propose that the temporal poles are involved in processing both words and pictures, but their engagement might be primarily determined by the level of specificity at which an object is processed. Activation in posterior temporal regions associated with picture processing most likely reflects intermediate, pre-semantic stages of visual processing. Our data are most consistent with a hierarchically structured, unitary system of semantic representations for both verbal and visual modalities, subserved by anterior regions of the inferior temporal cortex.     

A four-component model of procedural justice: defining the meaning of a "fair" process

Two studies test the prediction of the four-component model of procedural justice that people evaluate the fairness of group procedures using four distinct types of judgment. The model hypothesizes that people are influenced by two aspects of the formal procedures of the group: those aspects that relate to decision making and those that relate to the quality of treatment that group members are entitled to receive under the rules. In addition, people are hypothesized to be separately influenced by two aspects of the authorities with whom they personally deal: the quality of decision making by those authorities and the quality of the treatment that they receive from them. The results of two studies support the hypothesis of the four-component model by finding that all four of the procedural judgments identified by the model contribute to overall evaluations of the fairness of group procedures.     

Using Media to Create Experiential Learning in Multicultural and Diversity Issues

The authors present a framework for using media to create experiential learning in multicultural and diversity issues based on cognitive-experiential self-theory. They offer several lessons and a media resource list that are helpful in training counseling students in multicultural and diversity issues.
