Inviting the Significant Other of LGBT Clients into Substance Abuse Treatment Programs: Frequency and Impact

In the New York Metropolitan area, convenience samples of 194 LGBT and 107 heterosexual former clients of substance abuse programs were compared in regard to rate of invitation of their significant others into treatment for at least one session. No significant differences between sexual orientation groups were found. For LGBT respondents, inviting significant others into treatment resulted in improved program completion rates, greater satisfaction with treatment, enhanced feelings of counselor support, and higher abstinence rates at the end of treatment. For women, not having a significant other predicted higher abstinence rates at the end of treatment.     

Spatial attention as a necessary preliminary to early processes in reading.

One major theory of the relation between spatial attention and visual word recognition holds that the former is a necessary condition for the latter to begin. A different major theory asserts that although spatial attention can facilitate the latter, it is not a necessary condition. These two theories were pitted against each other experimentally. Spatial attention was operationalized in terms of the effect of a spatial precue on the time to name a target word that appeared above or below fixation. A masked prime word was presented before the target. The critical difference between experiments was cue validity (50% in Experiments 1a and 2a and 100% in Experiments 1b and 2b). Repetition priming was observed when the prime appeared in the uncued prime location in Experiments la and 2a but not in Experiments 1b or 2b. These results are inconsistent with the claim that visual word recognition does not depend on spatial attention. Discussion centres on the distribution of spatial attention across target locations as a function of cue validity.     

Nonmonotonic extrapolation in function learning

This article reports the results of an experiment addressing extrapolation in function learning, in particular the issue of whether participants can extrapolate in a nonmonotonic manner. Existing models of function learning, including the extrapolation association model of function learning (EXAM; E. L. DeLosh, J. R. Busemeyer, & M. A. McDaniel, 1997), cannot account for this type of extrapolation pattern. We present the results of an experiment in which participants were shown a series of paired stimulus-response magnitudes where the relationship between these 2 dimensions conformed to a cyclic function. Participants were shown to extrapolate from these training data in a nonmonotonic way, contrary to predictions from EXAM. A new model of function learning is presented, which predicts responses more accurately than EXAM.     

What do you do when things go right? The intrapersonal and interpersonal benefits of sharing positive events

Four studies examined the intrapersonal and interpersonal consequences of seeking out others when good things happen (i.e., capitalization). Two studies showed that communicating personal positive events with others was associated with increased daily positive affect and well-being, above and beyond the impact of the positive event itself and other daily events. Moreover, when others were perceived to respond actively and constructively (and not passively or destructively) to capitalization attempts, the benefits were further enhanced. Two studies found that close relationships in which one's partner typically responds to capitalization attempts enthusiastically were associated with higher relationship well-being (e.g., intimacy, daily marital satisfaction). The results are discussed in terms of the theoretical and empirical importance of understanding how people "cope" with positive events, cultivate positive emotions, and enhance social bonds.     

Ad hoc category restructuring

Participants learned to classify seemingly arbitrary words into categories that also corresponded to ad hoc categories (see, e.g., Barsalou, 1983). By adapting experimental mechanisms previously used to study knowledge restructuring in perceptual categorization, we provide a novel account of how experimental and preexperimental knowledge interact. Participants were told of the existence of the ad hoc categories either at the beginning or the end of training. When the ad hoc labels were revealed at the end of training, participants switched from categorization based on experimental learning to categorization based on preexperimental knowledge in some, but not all, circumstances. Important mediators of the extent of that switch were the amount of performance error experienced during prior learning and whether or not prior knowledge was in conflict with experimental learning. We present a computational model of the trade-off between preexperimental knowledge and experimental learning that accounts for the main results.     

ESI: Easy software interfacing tools for Turbo Pascal programming of digital input-output devices

We describe some programming tools for real-time monitoring and control of digital laboratory devices. These create several interrupt-driven processes that operate in the “background” of the user’s program. An event buffer logs switch closures, thus helping the user’s program keep up with events. Other simple commands (e.g., TurnOn) take a line number and a time argument as parameters; they are automatically executed at the time specified. Applications to operant conditioning are discussed.     

Toward a Metacognitive Account of Cognitive Offloading

Individuals frequently make use of the body and environment when engaged in a cognitive task. For example, individuals will often spontaneously physically rotate when faced with rotated objects, such as an array of words, to putatively offload the performance costs associated with stimulus rotation. We looked to further examine this idea by independently manipulating the costs associated with both word rotation and array frame rotation. Surprisingly, we found that individuals’ patterns of spontaneous physical rotations did not follow patterns of performance costs or benefits associated with being physically rotated, findings difficult to reconcile with existing theories of strategy selection involving external resources. Individuals’ subjective ratings of perceived benefits, rather, provided an excellent match to the patterns of physical rotations, suggesting that the critical variable when deciding on‐the‐fly whether to incorporate an external resource is the participant's metacognitive beliefs regarding expected performance or the effort required for each approach (i.e., internal vs. internal + external). Implications for metacognition's future in theories of cognitive offloading are discussed.
