A multistream model of visual word recognition

Four experiments are reported that test a multistream model of visual word recognition, which associates letter-level and word-level processing channels with three known visual processing streams isolated in macaque monkeys: the magno-dominated (MD) stream, the interblob-dominated (ID) stream, and the blob-dominated (BD) stream (Van Essen & Anderson, 1995). We show that mixing the color of adjacent letters of words does not result in facilitation of response times or error rates when the spatial-frequency pattern of a whole word is familiar. However, facilitation does occur when the spatial-frequency pattern of a whole word is not familiar. This pattern of results is not due to different luminance levels across the different-colored stimuli and the background because isoluminant displays were used. Also, the mixed-case, mixed-hue facilitation occurred when different display distances were used (Experiments 2 and 3), so this suggests that image normalization can adjust independently of object size differences. Finally, we show that this effect persists in both spaced and unspaced conditions (Experiment 4)—suggesting that inappropriate letter grouping by hue cannot account for these results. These data support a model of visual word recognition in which lower spatial frequencies are processed first in the more rapid MD stream. The slower ID and BD streams may process some lower spatial frequency information in addition to processing higher spatial frequency information, but these channels tend to lose the processing race to recognition unless the letter string is unfamiliar to the MD stream—as with mixed-case presentation.     

Perceived Racism as Moderator Between Self‐Esteem/Shyness and Psychological Distress Among African Americans

In the spirit of the mission of social justice in counseling, this study examined perceived racism as a moderator on the association between self‐concept (i.e., self‐esteem, shyness) and distress among African Americans. The authors examined whether perceived racism changed the relationship between self‐esteem/shyness and psychological distress by investigating a sample of 394 African Americans. With a moderation analysis, the authors found significant interaction effects of Self‐Esteem × Perceived Racism and Shyness × Perceived Racism on distress.     

“If I Didn't Have My Faith I Would Have Killed Myself!”: Spiritual Coping in Patients Suffering From Schizophrenia

Spirituality, religiousness, and existential thought were qualitatively investigated in six patients suffering from schizophrenia spectrum disorders. The present study is a deepening of a recently published quantitative investigation by Danbolt, Møller, Lien, and Hestad (2011) Danbolt, L., Møller, P., Lien, L. and Hestad, K. 2011. The personal significance of religiousness and spirituality in patients with schizophrenia. The International Journal for the Psychology of Religion, 21: 145–158. [Taylor & Francis Online], [Web of Science ®] , [Google Scholar]. The patients in the present study were chosen on the basis of diversity as to how they experienced their spirituality to be of significance when coping with their disorder. The informants displayed many signs of spiritual struggle and transitional spiritual coping strategies, all of which seemed to be linked to hallucinatory experiences. Even though their spirituality met the criteria of religious delusions, the patients described their spirituality to have vital importance. The informants showed little spiritual preknowledge and seemed to be left alone without any clerical support in their spiritual struggle. This may underline the importance of including spiritual issues in the treatment of these patients.     

Attentional capture by singletons is contingent on top-down control settings: Evidence from electrophysiological measures

The present study examined whether the capture of spatial attention is driven by stimulus salience (e.g., object uniqueness) or by a match to current attentional control settings (contingent capture). We measured the N2pc effect, a component of the event-related brain potential thought to reflect lateralized attentional allocation. On every trial, a noninformative cue display containing a colour singleton box was followed by a target display of letters. Participants searched for a target letter in a specified colour (in Experiments 1–3) or within a specified shape (in Experiment 4) while ignoring other stimuli. The key manipulation was whether the singleton cue contained the target-defining feature (e.g., a specific colour). Experiment 1 revealed signs of attention capture—a cue validity effect and an N2pc effect—only for singleton cues that contained the target-defining feature. This pattern persisted even when we increased the salience of the singleton box (Experiments 2 and 3). Irrelevant colour singletons also failed to produce a significant N2pc effect when the target was defined based on shape rather than colour (Experiment 4). We conclude that attention capture is strongly contingent on top-down attentional control settings, not bottom-up stimulus salience.     

The Role Behavioral of Activation and Inhibition in Explaining Adolescents’ Game Use and Game Engagement Levels

According to Gray’s reinforcement sensitivity theory, variations in the functioning of two neuropsychological systems, the behavioral approach (BAS) and inhibition (BIS) system, can result in individual differences in personality. Several studies have looked at associations between personality and media use but media research integrating BAS and BIS is scarce. The current cross-sectional survey study (n = 1016) representative for Belgian adolescents investigated associations between BAS and BIS and game use and game engagement in adolescents. Results showed that BAS was positively associated with playing both violent and nonviolent games. BIS was negatively associated with violent game use while it was positively associated with nonviolent games. Also, BAS was positively associated with game engagement. No association was found between BIS and game engagement. Game engagement was shown to mediate the relationship between BAS and playing both violent and nonviolent games. Based on these results, the present study argues that integrating the reinforcement sensitivity theory in media research makes an important contribution to the understanding of the link between personality and game engagement and game use.     

The antecedents and belief-polarized effects of thought confidence

This article investigates 2 possible antecedents of thought confidence and explores the effects of confidence induced before or during ad exposure. The results of the experiments indicate that both consumers' dispositional optimism and spokesperson attractiveness have significant effects on consumers' confidence in thoughts that are generated after viewing the advertisement. Higher levels of thought confidence will influence the quality of the thoughts that people generate, lead to either positively or negatively polarized message processing, and therefore induce better or worse advertising effectiveness, depending on the valence of thoughts. The authors posit the belief-polarization hypothesis to explain these findings.     

Aging and involuntary attention capture: electrophysiological evidence for preserved attentional control with advanced age

The present study examined whether people become more susceptible to capture by salient objects as they age. Participants searched a target display for a letter in a specific color and indicated its identity. In Experiment 1, this target display was preceded by a non-informative cue display containing one target-color box, one ignored-color box, and two white boxes. On half of the trials, this cue display also contained a salient-but-irrelevant abrupt onset. To assess capture by the target-color cue, we used the N2pc component of the event-related potential, thought to reflect attentional allocation to the left or right visual field. The target-color box in the cue display produced a substantial N2pc effect for younger adults and, most importantly, this effect was not diminished by the presence of an abrupt onset. Therefore, the abrupt onset was unable to capture attention away from the target-color cue. Critically, older adults demonstrated the same resistance to capture by the abrupt onset. Experiment 2 extended these findings to irrelevant color singleton cues. Thus, we argue that the ability to attend to relevant stimuli and resist capture by salient-but-irrelevant stimuli is preserved with advancing age.     

The Sources of Meaning and Meaning in Life Questionnaire in the Norwegian Context: Relations to Mental Health,Quality of Life,and Self-Efficacy

The Sources of Meaning and Meaning in Life Questionnaire (SoMe) offers dimensional measures of meaningfulness, crisis of meaning, and 26 sources of meaning. It allows for a clearer understanding of the variety of existential orientations, which are known to be linked to both mental and physical health. The Norwegian version of the SoMe was validated by testing 925 randomly selected individuals who were representative for the Norwegian population. Reliability scores were satisfactory; factor analyses suggested a 6-factor structure of the sources of meaning scales. Expected patterns of associations with mental health and quality-of-life factors attested the instrument’s construct validity: Meaningfulness showed positive relationships to all quality-of-life factors. There was no relationship with anxiety but negative relationships with depression and distress. Crisis of meaning established a strong positive relationship with anxiety, depression, and distress and a negative relationship with quality-of-life factors. Criterion validity was documented by expected differences in meaningfulness and crisis of meaning between groups with and without presence of depression disorder. Self-efficacy correlated strongly with sources of meaning from the dimension “accomplishment” and moderately negatively with sources of meaning from the dimension “vertical selftranscendence.”     

Ideomotor compatibility in the psychological refractory period effect: 29 years of oversimplification

Four experiments examined whether the psychological refractory period (PRP) effect can be eliminated with ideomotor compatible (IM) but not stimulus-response compatible (SR) tasks, as reported by A. G. Greenwald and H. G. Shulman (1973). Their tasks were used: a left or right movement to a left- or right-pointing arrow (IM) or to the word left or right (SR) for Task 1; saying "A" or "B" (IM) or "1" or "2" (SR) to an auditory A or B for Task 2. The stimulus onset asynchronies were 0, 100, 200, 300, 500, and 1,000 ms in Experiment 1, and only 0, 100, 200, and 1,000 ms in Experiments 2-4. The arrow was in the center of the screen in Experiments 1-3 and to the left or right in Experiment 4. As in Greenwald and Shulman's Experiment 2, the instructions stated that most often the 2 stimuli would be presented simultaneously. A PRP effect was obtained in all conditions, most likely because response-selection decisions are required even for IM tasks.     

Still no evidence for perfect timesharing with two ideomotor-compatible tasks: a reply to Greenwald (2003)

For 30 years, A. G. Greenwald and H. G. Shulman's (1973) psychological refractory period (PRP) study has been cited as evidence for perfect timesharing with ideomotor (IM)-compatible tasks. Recently, M.-C. Lien, R. W. Proctor, and P. A. Allen (2002) failed to replicate these results and concluded that IM compatibility is neither necessary nor sufficient to eliminate the PRP effect. A. G. Greenwald (2003) attributed Lien et al.'s nonreplication to the use of (a) a non-IM-compatible task, (b) varied trial spacing, and/or (c) inappropriate instructions. The authors of the present article argue that the first 2 factors are not critical and that instructions merely affect the criterion for speed versus accuracy. In each of Greenwald's experiments, dual-task costs were evident on response time or error rates. Furthermore, the small dual-task costs in his study are consistent with a bottleneck model. Thus, Greenwald (2003) does not provide evidence that IM-compatible tasks enable perfect timesharing.
