Attention versus consciousness in the visual brain: differences in conception, phenomenology, behavior, neuroanatomy, and physiology.

A common confound between consciousness and attention makes it difficult to think clearly about recent advances in the understanding of the visual brain. Visual consciousness involves phenomenal experience of the visual world, but visual attention is more plausibly treated as a function that selects and maintains the selection of potential conscious contents, often unconsciously. In the same sense, eye movements select conscious visual events, which are not the same as conscious visual experience. According to common sense, visual experience is consciousness, and selective processes are labeled as attention. The distinction is reflected in very different behavioral measures and in very different brain anatomy and physiology. Visual consciousness tends to be associated with the "what" stream of visual feature neurons in the ventral temporal lobe. In contrast, attentional selection and maintenance are mediated by other brain regions, ranging from superior colliculi to thalamus, prefrontal cortex, and anterior cingulate. The author applied the common-sense distinction between attention and consciousness to the theoretical positions of M. I. Posner (1992, 1994) and D. LaBerge (1997, 1998) to show how it helps to clarify the evidence. He concluded that clarity of thought is served by calling a thing by its proper name.     

Patterns of attachment and parents' adjustment to the death of their child

The impact of adult attachment on psychological adjustment among bereaved parents and the mediating effect of relationship satisfaction were examined among a sample of 219 couples of parents. Data collection took place 6, 13, and 20 months after loss. Use of the actor partner interdependence model in multilevel regression analysis enabled exploration of both individual as well as partner attachment as predictors of grief and depression. Results indicated that the more insecurely attached parents were (on both avoidance and anxiety attachment), the higher the symptoms of grief and depression. Neither the attachment pattern of the partner nor similarity of attachment within the couple had any influence on psychological adjustment of the parent. Marital satisfaction partially mediated the association of anxious attachment with symptomatology. Contrary to previous research findings, avoidant attachment was associated with high grief intensity. These findings challenge the notion that the avoidantly attached are resilient.     

The size of the Simon effect depends on the nature of the relevant task

Four experiments were conducted to investigate contextual modulations of the Simon effect. The results showed that the Simon effect was quantitatively different depending on which kind of task needed to be performed. Importantly, this effect did not depend on the relative processing time of the relevant dimension, nor on a direct or indirect overlap between the relevant and irrelevant stimulus part. To account for the data, we refer to the neural overlap hypothesis, which extends the definition of dimensional overlap (Kornblum, Hasbroucq, & Osman, 1990) with similarity of processing regions as the key factor for the interaction between relevant and irrelevant information processing.     

A conceptual and theoretical analysis of evaluative conditioning

Evaluative conditioning is best defined as an effect, that is, as a change in the valence of a stimulus that results from pairing the stimulus with another stimulus. This definition has several advantages that are made explicit in this paper. One of the advantages is that it clarifies that evaluative conditioning can be due to multiple processes. Therefore, the conditions under which evaluative conditioning is observed can depend on the processes that underlie a particular manifestation of evaluative conditioning. This could explain why there are so many conflicting results about the conditions under which evaluative conditioning can be found. Future research should adopt a meta-conditional approach that focuses not only on whether a certain condition is crucial for obtaining evaluative conditioning but should also examine when a certain condition is crucial.     

Rorschach Comprehensive System data for a sample of 141 adult nonpatients from Denmark

A sample (n = 141) of Danish nonpatients 25-50 years of age, never hospitalized with a psychiatric diagnosis and currently employed, was demographically representative of two geographical areas of Copenhagen with different social strain. The sample, as well as 45 persons not currently employed, was tested with the Rorschach (Exner, 1995), MMPI-2 (Butcher, Dahlstrom, Graham, Tellegen, & Kaemmer, 1989), Word Association Test (Ivanouw, 1999b), WAIS Comprehension subtest (Hess, 1974), and SCL-90-R (Olsen, Mortenson, & Bech, 2006). Half of the persons contacted volunteered for the study. There was no difference in rate of volunteering between a standard no-feedback condition and a feedback condition; the latter, however, tended to attract more psychologically resourceful persons. The employed persons tended to appear healthier than the not employed. Response style of the subjects, quality of the Rorschach protocols, reliability of scoring, and the effect of the data being grouped on geographical area and examiner were examined. Form level, color, texture, cooperative movement, and EA were lower than in the Comprehensive System (CS; n = 450) sample, but higher than in nine international nonpatient Rorschach studies. Unique for the Danish sample was a low number of animal movement answers. The Rorschach data showed women to be healthier than men. Differences in Rorschach variables based on educational level were small.
