Magnitude estimations of the course of gustatory adaptation

Magnitude estimations of 15-sec intervals were obtained during 2-min and 5-min adaptation of suprathreshold solutions of NaCl. quinine sulfate (QSO₄, and sucrose. Expectorating and adding fresh adapting solution at the end ofeach minute produced higher estimations than those obtained with continuous adaptation because of salivary dilution. Separation of the adaptation determinations by 45-sec rest intervals rather than 5 min had no effect on the form or magnitude of the functions for NaCl or sucrose, although QSO₄. adaptations separated by the shorter rest intervals were of greater magnitude. The absence of complete adaptation was largely attributed to the effects of tongue movements.     

The roles of practice and correction in the categorization of sour and bitter taste qualities

Ten Ss were selected from a group of 40 screened to determine misnaming of stimuli usually called sour (hydrochloric and citric acid) and bitter (quinine sulfate). The 10 Ss were then given 16 trials in which they were asked to match the stimuli to standards, with or without verbal feedback for each stimulus. This was followed by 16 trials without feedback for all Ss and, several days later, by a 16-trial posttest. Final improved performance of the Ss was not affected by having received the feedback. It was concluded that experience with the stimuli leads to a reduction in the degree of misnaming, implying a nonphysiological basis for sour-bitter confusions.     

The common factors in fifty-two mental tests

An analysis by Thurstone's centroid method of the intercorrelations of fifty-two tests was carried to ten factors. Included were tests of social intelligence, Philip's attention tests, and Seashore's tests of musical ability. After rotation of axes, the most important factors appeared to pertain to operations conventionally alluded to by the following terms: verbal facility; spatial ability; numerical ability; attention; musical ability; and memory (or memory span). The social intelligence tests proved to be mainly tests of the verbal factor. A factorial sex difference was indicated by the superiority of men in tests of spatial ability.     

Testing the Factor Structure and Measurement Invariance Across Gender of the Big Five Inventory Through Exploratory Structural Equation Modeling

Confirmatory factor analyses (CFAs) typically fail to support the a priori 5-factor structure of Big Five self-report instruments, due in part to the overly restrictive CFA assumptions. We show that exploratory structural equation modeling (ESEM), an integration of CFA and exploratory factor analysis, overcomes these problems in relation to responses to the 44-item Big Five Inventory (BFI) administered to a large Italian community sample. ESEM fitted the data better and resulted in less correlated factors than CFA, although ESEM and CFA factor scores correlated at near unity with observed raw scores. Tests of gender invariance with a 13-model taxonomy of full measurement invariance showed that the factor structure of the BFI is gender-invariant and that women score higher on Neuroticism, Agreeableness, Extraversion, and Conscientiousness. Through ESEM one could address substantively important issues about BFI psychometric properties that could not be appropriately addressed through traditional approaches.     

Spontaneous Goal Inference (SGI)

When people learn about or observe the behaviors of others, they tend to make implicit inferences from these behaviors (e.g., Uleman, Saribay, & Gonzalez, 2008). Such inferences are an essential part of a person's ability to understand his/her environment and to prepare appropriate behavior within that environment. In the present paper, we review the conditions under which people are more likely to make implicit goal inferences versus implicit trait inferences. The distinction between these two ways of understanding the behavior we observe has important consequences for how we make predictions about future behavior, set expectations for our interaction partners, and how we choose to behave. It can determine when we stereotype. However, until now, the literature has focused on trait inference as the dominant way perceivers make sense of their environment, with little discussion of inferences concerning a person's goals.     

Clinical Exchange: The Architectural Failure

The Clinical Exchange invites eminent clinicians of diverse persuasions to share, in ordinary language, their clinical formulations and treatment plans of the same psychotherapy patient—one not selected or nominated by those therapists—and then to discuss points of convergence and contention in their recommendations. This Exchange concerns a Mr. L, a 47-year-old, married man presenting for outpatient individual psychotherapy with chief complaints of depression, anxiety, and a lengthy history of vocational underachievement. Drs. Herbert Fensterheim, Leslie Greenberg, and Leigh McCullough, who anchor their practices in the cognitive-behavioral, experiential, and psychodynamic orientations, respectively, are the featured commentators. Finally, Dr. Jerold Gold, the case contributor and Mr. L's psychotherapist, provides a few closing comments.     

The Ontogeny of Long‐Term Retention During the Second Year of Life

Developmental changes in retention were assessed in two experiments with 18‐ and 24‐month‐old infants. In both experiments, infants were tested in a deferred imitation paradigm. In Experiment 1, independent groups of infants were tested either immediately or after delays of 1, 14, 28 or 56 days. There was no age‐related difference in the spontaneous production of target actions (baseline) or in immediate imitation. There were age‐related changes in retention after longer delays. Eighteen‐month‐olds exhibited retention for 14 days and 24‐month‐olds exhibited retention for at least 56 days. In Experiment 2, the maximum duration of retention by 24‐month‐olds was assessed. Independent groups of infants were tested after 3 or 6 months. Infants exhibited some evidence of retention after 3 months; however, forgetting was complete after 6 months.
