The time course of contextual influences during lexical ambiguity resolution: Evidence from distributional analyses of fixation durations

In the lexical ambiguity literature, it is well-established that readers experience processing difficulties when they encounter biased homographs in a subordinate-instantiating prior context (i.e., the subordinate bias effect). To investigate the time course of this effect, the present study examined distributional analyses of first-fixation durations on 60 biased homographs that were each read twice: once in a subordinate-instantiating context and once in a dominant-instantiating context. Ex-Gaussian fitting revealed that the subordinate context distribution was shifted to the right of the dominant context distribution, with no significant contextual differences in the degree of skew. In addition, a survival analysis technique showed a significant influence of the subordinate versus dominant contextual manipulation as early as 139?ms from the start of fixation. These results indicate that the contextual manipulation had a fast-acting influence on the majority of fixation durations, which is consistent with the reordered access model's assumption that prior context can affect the lexical access stage of reading.     

Measuring the time course of selection during visual search

In visual search tasks, observers can guide their attention towards items in the visual field that share features with the target item. In this series of studies, we examined the time course of guidance toward a subset of items that have the same color as the target item. Landolt Cs were placed on 16 colored disks. Fifteen distractor Cs had gaps facing up or down while one target C had a gap facing left or right. Observers searched for the target C and reported which side contained the gap as quickly as possible. In the absence of other information, observers must search at random through the Cs. However, during the trial, the disks changed colors. Twelve disks were now of one color and four disks were of another color. Observers knew that the target C would always be in the smaller color set. The experimental question was how quickly observers could guide their attention to the smaller color set. Results indicate that observers could not make instantaneous use of color information to guide the search, even when they knew which two colors would be appearing on every trial. In each study, it took participants 200–300 ms to fully utilize the color information once presented. Control studies replicated the finding with more saturated colors and with colored C stimuli (rather than Cs on colored disks). We conclude that segregation of a display by color for the purposes of guidance takes 200–300 ms to fully develop.     

Primacy of information about means selection over outcome selection in goal attribution by infants

It has been shown that, when observing an action, infants can rely on either outcome selection information (i.e., actions that express a choice between potential outcomes) or means selection information (i.e., actions that are causally efficient toward the outcome) in their goal attribution. However, no research has investigated the relationship between these two types of information when they are present simultaneously. In an experiment that addressed this question directly, we found that when outcome selection information could disambiguate the goal of the action (e.g., the action is directed toward one of two potential targets), but means selection information could not (i.e., the action is not efficiently adjusted to the situational constraints), 7- and 9-month-old infants did not attribute a goal to an observed action. This finding suggests that means selection information takes primacy over outcome selection information. The early presence of this bias sheds light on the nature of the notion of goal in action understanding.     

Time course of recovery from gustatory adaptation to NaCl

Recovery from adaptation to NaCl was tested by comparing some relevant parameters of response to the adapting and test stimuli separated by different recovery intervals. The time course of response was determined using magnitude estimations and using the flow chamber for stimulus delivery. The course of recovery for all parameters used was a negatively accelerated function of the rest time, but the recovery rate of different parameters did not prove to be equal. Recovery was fastest for the initial maximum taste magnitude, followed by the time needed for the taste to disappear. The taste effect summed over time and the time required for the taste magnitude to decrease to 30% of its preadapted maximum were the slowest to recover. Although the recovery process proceeded at a rapid rate during the initial period, all parameters remained depressed over a rather long period.     

Psychological hardiness predicts successful selection in a law enforcement special operations assessment and selection course

We studied the predictive effects of psychological hardiness on successful selection in a United States federal tactical law enforcement assessment and selection (A&S) program. Seventy‐one male experienced law enforcement personnel participated in a week‐long, physically and psychologically rigorous A&S course. Dispositional Resilience Scale (DRS‐15) Total Hardiness scores predicted selection in this select sample. Age and cognitive ability moderated the predictive effects of psychological hardiness such that hardiness predicted selection in younger candidates and candidates with higher cognitive ability. Similar findings were obtained for DRS Commitment. DRS‐15 Control facet also differentiated selection in this sample but the predictive effects did not hold when age and cognitive ability were controlled. Findings extend the application of the DRS‐15 to law enforcement personnel selection and highlight the importance of examining moderating effects of psychological hardiness.     

Personality disorders over time: precursors, course and outcome

Personality disorders cause dysfunction over the course of adult life. A chronic course of disorder tends to be associated with an early onset, and personality disorders are preceded by precursor symptoms in childhood. Long-term outcome varies by personality disorder category: antisocial and borderline personality tend to remit with age, an improvement that is not seen in other diagnoses. The chronicity of personality disorders can usefully guide treatment planning, and psychotherapy for personality disorders can focus on rehabilitation.

The time course of grief reactions to spousal loss: evidence from a national probability sample

Most studies of widowhood have focused on reactions during the first few years postloss. The authors investigated whether widowhood had more enduring effects using a nationally representative U.S. sample. Participants were 768 individuals who had lost their spouse (from a few months to 64 years) prior to data collection. Results indicated that the widowed continued to talk, think, and feel emotions about their lost spouse decades later. Twenty years postloss, the widowed thought about their spouse once every week or 2 and had a conversation about their spouse once a month on average. About 12.6 years postloss, the widowed reported feeling upset between sometimes and rarely when they thought about their spouse. These findings add to an understanding of the time course of grief.     

The relative influence of attitudes and subjective norms from childhood to adolescence: between-participant and within-participant analyses

Children and adolescents (ages 8-16) were asked to indicate their behavioral intentions, attitudes, and subjective norms for 34 behaviors. Between-participant and within-participant analyses demonstrated that attitudes and subjective norms were good predictors of behavioral intentions both singly and in combination. In addition, attitudes generally were better predictors than were subjective norms both across behaviors and across participants. Most importantly, however, there were no differences in the relative importance of attitudes and subjective norms in predicting behavioral intentions across age groups.     

The capacity to be an analyst: A contribution from attachment research to the study of candidate selection

In this paper the author discusses how the study of candidate selection, once a topic of vibrant research, has unfortunately languished. Certain qualities were thought to characterize the successful candidate. However, they were never successfully operationalized nor empirically tested. Possibly because of this lack of empirical data, selectors today have difficulty articulating their criteria and are relying on intuition. In order to provide a more rational basis for contemporary selection, the author looks to the attachment literature. This makes sense because attachment theory shares some basic assumptions of contemporary psychoanalysis. The Adult Attachment Interview (AAI) is a research tool that predicts the ability of a parent to convey attachment security. It is scored by attending to how a person speaks about his early attachment experiences. The AAI appears to tap into similar qualities to those selection researchers have sought in their candidates. Further, the scoring method of the AAI appears to be similar to the last attempt by selection researchers to operationalize them. Given these similarities, the author recommends an empirical study using the AAI to operationalize these qualities in analytic candidates. The study would test their importance for success in the training program, thus offering selectors some empirical grounding for their choices.     

Time course of movement planning: selection of handgrips for object manipulation.

A goal of research on the cognitive control of movement is to determine how movements are chosen when many movements are possible. We addressed this issue by studying how subjects reached for a bar to be moved as quickly as possible from a home location to a target location. Ss generally grabbed the bar in a way that afforded a comfortable posture at the target location (the end-state comfort effect) and with the thumb toward the end of the bar that would be aligned with the target (the thumb-toward bias). The data suggested that subjects chose handgrips by retrieving instances of previous reaches, not by carrying out computations that treated candidate reaches as new behavioral events.     

Effect of uncertainty on the time course for selection of verbal name codes

Response selection takes time. Hick's law (Hick, 1952) predicts that the time course of response selection is a logarithmic function of the number of equally likely response alternatives. However, recent work has shown that oculomotor responses constitute noteworthy exceptions in that the latencies of saccades (Kveraga, Boucher, & Hughes, 2002) and smooth pursuit movements (Berryhill, Kveraga, Boucher, & Hughes, 2004) are completely independent of response uncertainty. This finding extends to the case in which the required response was known in advance (i.e., simple reaction times [RTs] were equivalent to choice RTs). In view of these results, we reevaluated reports that latencies to name visually presented digits (Experiment 1) and/or repeat aurally presented digits (Experiment 2) are similarly independent of the size of the response set. We found that naming latencies were equivalent for response set sizes from one to eight, but simple RTs (response set of one) were faster. Thus, the overlearned task of digit naming is indeed highly automatic but has not reached the level of automaticity characteristic of the oculomotor system.     

The relation between formal operational reasoning and academic course selection and performance among college freshmen and sophomores

The significance of Inhelder and Piaget's (1958) construct of “formal operations” depends in part on establishing the extent to which formal operations have real-world relevance beyond the narrow domain of assessment situations in which Inhelder and Piaget studied them. The present research investigates this question by examining the effect of exhibiting a concrete versus formal operational level of reasoning in an isolation of variables task on academic program selection and performance of beginning college students over a two-year period. Students who reasoned at the concrete operational level did not differ from students matched on ACT scores who reasoned at a formal operational level with respect to either number of college credits obtained or overall grade point average. When courses were broken down into three categories, however, “formals” took significantly more science/math courses and received significantly higher grades in them. No differences were found in the other two categories: liberal arts/social sciences or activities/vocational courses. A further study of beginning college students already enrolled in science/math courses confirmed that very few concrete operational reasoners were present in these courses, suggesting that a process of self-selection is in operation.     

From outcome prediction to action selection: developmental change in the role of action–effect bindings

Ideomotor theory considers bidirectional action–effect associations to be the fundamental building blocks for intentional action. The present study employed a novel pupillometric and oculomotor paradigm to study developmental changes in the role of action‐effects in the acquisition of voluntary action. Our findings suggest that both 7‐ and 12‐month‐olds (and adults) can use acquired action–effect bindings to predict action outcomes but only 12‐month‐olds (and adults) showed evidence for employing action‐effects to select actions. This dissociation supports the idea that infants acquire action–effect knowledge before they have developed the cognitive machinery necessary to make use of that knowledge to perform intentional actions.     

An approach to the study of analyzability and analyses: the course of forty consecutive cases selected for supervised analysis.

The cases of 40 consecutive patients, accepted for supervised psychoanalysis at the Treatment Center of The New York Psychoanalytic Institute, are reviewed. The process of the initial evaluation is examined as well as the nature of the patient group, the characteristics of the treatment, outcome, and follow-up data. A survey of a group of 42 patients from the private practice of a group of graduate analysts during the same period of time is also reported. Both studies are discussed in relation to methodological issues, and an approach is suggested for the study of assessment of analyzability and analyses through a systematic prospective study of analytic treatments conducted by experienced analysts.
