Overview of NIMH support of research in behavior therapy

Many parts of the National Institute of Mental Health have explicit policies of encouraging research on behavior therapy. The policies about behavior therapy research of sub-units of NIMH are reviewed, as these policies existed in fiscal year 1973. Examples are given of the type of behavior therapy research that NIMH was supporting in 1972. Particularly important is the evaluation of the efficacy of behavior therapy in comparison with standard treatment procedures.     

Economics of religion on trial: how disestablishment did not lead to religious revival in the Swiss cantons of Geneva and Neuchâtel

According to ideas in contemporary economics of religion, religious disestablishment will lead to religious vitality: more strictness, more evangelising, and more growth. The present article puts this theory to the test by inspecting the historical record (1900 to the present) of the two Swiss cantons where disestablishment went farthest—Geneva and Neuchâtel—and by comparing them to other Swiss cantons where church and state remained closely linked. I find that the predictions of the economic model are not corroborated. Formerly established churches did not become stricter, did show increased, but relatively unsuccessful marketing efforts, did not grow, and became very poor financially. Non-established churches did not seem to benefit in any way from the disestablishment. The article makes four specific theoretical points that explain why this was the case.     

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.     

Context dependency in Stroop's paradigm: when are words treated as nonlinguistic objects?

The "memory" literature emphasizes the notion of encoding variability, whereas the "word recognition and attention" literature typically asserts that it is impossible to prevent immediate lexical and semantic activation when single words are presented to skilled readers. In the four experiments reported here, the presence/absence of a Stroop effect was associated with the nature of the between-trial context. These data can be understood as an expression of contextually driven encoding variability, but are problematic for the decontextualized "automatic" processing account that has prevailed in the attention and performance literature for the last six decades.     

On the Nature of Cognitive Control and Endogenous Orienting: A Response to Chica and Bartolomeo (2010)

Chica and Bartolemeo (Unconscious strategies? Commentary on Risko and Stolz (2010): The proportion valid effect in covert orienting: Strategic control or implicit learning? Consciousness and Cognition, 19, 443–444.) agree that our results (Risko, E. F., & Stolz, J. A. (2010). The proportion valid effect in covert orienting: Strategic control or implicit learning? Consciousness and Cognition, 19, 432–442.) are consistent with an implicit learning account of the proportion valid effect. Nevertheless, they raise two general issues (1) that an explicit strategy might be operative in other contexts and (2) that orienting in response to implicit knowledge is endogenous. In our response, we address each of these issues and further discuss the concepts of endogenous orienting and cognitive control.     

Nonstrategic contributions to putatively strategic effects in selective attention tasks

Proportion compatible manipulations are often used to index strategic processes in selective attention tasks. Here, a subtle confound in proportion compatible manipulations is considered. Specifically, as the proportion of compatible trials increases, the ratio of complete repetitions and complete alternations to partial repetitions increases on compatible trials but decreases on incompatible trials. This confound is demonstrated to lead to an overestimation in the magnitude of the proportion compatible effect in the context of both a Stroop and a Simon task. Implications for previous research and directions for future research using proportion compatible manipulations are discussed.     

Covert orienting: A compound-cue account of the proportion cued effect

An increase in the proportion of spatially cued trials in the context of the covert orienting paradigm increases the magnitude of the cuing effect. This proportion cued effect is widely interpreted to reflect a form of control. Specifically, it is argued that participants strategically allocate attention as a function of the utility of the spatial cue. Here, an alternative explanation of the proportion cued effect is proposed that does not require control. According to this account, the cue-target event forms a compound cue and the proportion cued manipulation produces a relative disparity in the frequency with which particular compound cues occur. Specifically, when the proportion of spatially cued trials is increased, the frequency of spatially cued cue-target events increases and the frequency of spatially miscued cue-target events decreases, thus increasing the magnitude of the cuing effect. The results of two experiments support this account.     

Calling all codes: interactive effects of semantics, phonology, and orthography produce dissociations in a repetition blindness paradigm

We used the repetition blindness (RB) paradigm to examine the roles of semantics, phonology, and orthography on report from rapidly presented 5-item word lists. Semantic primes in positions 1 and 3 in the list preceded homographic homophones, homographic heterophones, and heterographic homophones as critical targets in positions 2 and 4. All codes (i.e., semantic, phonologic, and orthographic) were repeated, or meaning changed while only phonology, only orthography, or both were repeated for the critical targets. Using a scoring procedure that considered order of report, we assessed facilitation for report of the first instance of the repeated target (a novel aspect of our procedure) and RB for report of the second instance of the repeated target. Except when accompanied by a change in orthography, a change in meaning reduced RB relative to when all codes were repeated. Facilitation in the report of the first instance of the repeated item occurred only if meaning changed and phonology was repeated (independent of whether orthography changed). Finally, recall was worse for the meaning change nonrepeated control lists (which instantiated 3 unrelated meanings in the list, including the last unrelated item) than for the no-meaning change control lists (which instantiated 2 unrelated meanings). We discuss the relevance of these findings for extant accounts of repetition blindness.
