Instructions and stimulus categorizing in a measure of stimulus generalization

In Experiment I, three groups of 20 Ss each were exposed to a light of 550 mμ (yellowish-green) for 60 sec and then viewed a random sequence of wavelengths with instructions to respond only to the original color. The instructions given the three groups were worded differently in an attempt to vary the strength of a set-to-discriminate assumed to be created by this procedure. The three groups produced similar gradients, each with a peak of responding at 540 mμ, in agreement with Kalish's (1958) published gradient for the 550 mμ standard stimulus value. It was suggested that the nature of the task is such that a strong discriminatory set is produced regardless of the wording of the instructions.

A temporal analysis of the gradient as it develops during the testing revealed that initially the peak of responding occurs at 550 mμ; but as testing progresses, it shifts gradually in the direction of the shorter wavelengths (purer greens). Experiment II was performed to test the generality of the phenomenon of regression to the primary color. Two groups of 20 Ss each were tested for generalization following exposure to 510 mμ (bluish-green) and 525 mμ (pure green), respectively. We predicted that the 510 mμ gradient would reveal a progressive shift toward the longer wavelengths (purer greens), whereas the 525 mμ gradient would show no tendency to shift. The results were strikingly in accord with these predictions.

We concluded that although a physiological process could not be ruled out, the verbal labeling of the standard stimulus value may well be responsible for the regression of the gradient toward the primary color.

     

Evolution and process of spiritual awakening: A grounded theory study

The present study used a constructivist grounded theory (CGT) approach to explore, examine and develop a grounded theory (GT) of spiritual awakening conceptualisation and process. The authors used the interview data of 34 eminent spiritual teachers who have written books on spirituality, led spiritual retreats and conducted lectures and trainings on spiritual quest. These participants come from diverse backgrounds (e.g., American, Asian, European and Mexican), trainings (e.g., Buddhism, Yoga, Hinduism, Taoism, Christianity and other mindfulness traditions) and professional experiences. The data analysis of the interviews led to the development of the spiritual awakening evolution (SAE) model, explaining the process and evolution of spiritual awakening. According to this model, spiritual awakening evolves through four phases: an initial transient shift in perception, further practice to support spiritual development, surrendering and a continuous journey of spiritual development. As spiritual awakening experiences are transcultural, the SAE model can inform counsellors' understanding of clients' spiritual needs and the meanings of those experiences. Implications for counsellor practitioners, counsellor preparation programmes and research are discussed.     

Syntactic prediction during self-paced reading is age invariant

Controversy exists as to whether, compared to young adults, older adults are more, equally or less likely to make linguistic predictions while reading. While previous studies have examined age effects on the prediction of upcoming words, the prediction of upcoming syntactic structures has been largely unexplored. We compared the benefit that young and older readers gain when the syntactic structure is made predictable, as well as potential age differences in the costs involved in making predictions. In a self-paced reading study, 60 young and 60 older adults read sentences in which noun-phrase coordination (e.g. large pizza or tasty calzone) is made predictable through the inclusion of the word either earlier in the sentence. Results showed a benefit of the presence of either in the second half of the coordination phrase, and a cost of the presence of either in the first half. We observed no age differences in the benefit or costs of making these predictions; Bayes factor analyses offered strong evidence that these effects are age invariant. Together, these findings suggest that both older and younger adults make similar strength syntactic predictions with a similar level of difficulty. We relate this age invariance in syntactic prediction to specific aspects of the ageing process.     

Thinking of threats: Economic threat appraisals and health threat appraisals predict differential racial attitudes during COVID-19

We examined whether perceptions of the health and economic threats posed by COVID-19 predict different patterns of intergroup attitudes, using data gathered during the early phase of the pandemic. Using data from 1339 geographically and politically diverse White US residents, we show that subjective economic threat predicted general anti-outgroup attitudes, while subjective health threat predicted negative attitudes towards both Asian and Latinx (“stereotypically foreign”) outgroups but not towards other outgroups. Among 303 geographically and politically diverse Black US residents, the pattern instead suggested that threat (regardless of type) was associated with reduced evaluative differentiation between racial ingroups and outgroups.     

Shame, Guilt, Ego Development and the Five-Factor Model of Personality

Shame, guilt, and ego development are conceptually interrelated constructs, yet their empirical relations have not yet been examined. Further, these constructs have not yet been mapped onto the widely used Five-Factor Model. In Study 1, relations were examined between these three domains within a sample of Australian university students. Two types of guilt were distinguished, Empathic Guilt (associated with Agreeableness) and Anxious Guilt (associated with Neuroticism). The relationship between Shame and Ego Level was found to be curvilinear, with Shame greatest for persons at intermediate stages of ego development. In Study 2, relations between ego development and the Five-Factor Model were further examined. Across both studies, Ego Level was best predicted from Conscientiousness among men and from Openness among women. Relations between Ego Level, proneness to shame and guilt, and the five factors were typically modest, suggesting that these represent complementary approaches to the study of personality.     

FIXED-TIME SCHEDULES ATTENUATE EXTINCTION-INDUCED PHENOMENA IN THE TREATMENT OF SEVERE ABERRANT BEHAVIOR

We compared the effects of extinction (EXT) and fixed-time (FT) schedules as treatment for severe problem behavior displayed by 3 individuals with developmental disabilities. First, functional analyses identified the reinforcers maintaining aberrant behavior for all 3 individuals. Next, EXT and FT schedules were compared using a multielement design. During EXT, the reinforcer maintaining problem behavior was withheld. During FT, the reinforcers were presented response independently at preset intervals. Results showed that FT schedules were generally more effective than EXT schedules in reducing aberrant behavior. FT schedules may be used in situations when extinction-induced phenomena are problematic.     

Impact of Rater Beliefs Regarding Performance Appraisal and Its Organizational Context on Appraisal Quality

The relationship between attitudes and beliefs regarding performance appraisal and its organizational context and three measures of rating quality (i.e., rating level, discrimination among ratees, discrimination among rating dimensions) were examined. Eighteen of twenty-four directional predictions about the correlations between attitudinal measures and rating behavior measures were supported. However, because of the expected weak to moderate relationships between predictors and criteria and the use of small samples, statistical power was generally low, and many of the individual observed correlations failed to reach significance. Nevertheless, the consistent pattern of support for the directional predictions suggests that the attitudes and beliefs studied here provide a useful basis for understanding performance appraisal behaviors.     

Posthypnotic Responding Away from the Hypnotic Setting

We examined posthypnotic suggestion away from the laboratory. In Experiment 1, high-hypnotizable subjects were given a posthypnotic suggestion (of limited or unlimited duration) or a social request (of unlimited duration) to mail one postcard every day to the experimenter. Subjects given a social request rather than a posthypnotic suggestion sent more postcards, and those given a limited-duration suggestion responded differently from those given an unlimited-duration suggestion. In Experiment 2, real, hypnotized and simulating, unhypnotized subjects were given a posthypnotic suggestion, and nonhypnotic control subjects were given a social request, to mail one postcard every day; the suggestion or request was of either limited or unlimited duration. Real, hypnotized subjects sent more postcards than simulators; control subjects sent as many postcards as real, hypnotized subjects; and subjects given a suggestion or request of limited duration sent more than those given one of unlimited duration. The findings highlight the interaction of individual differences and the social context of the suggestion or request. They underscore important aspects of experience and behavior associated with posthypnotic responding away from the hypnotic setting.     

Increasing the benefits of eye-tracking devices in divided visual field studies of cerebral asymmetry

A wide range of methods has been proposed for ensuring central fixation in divided visual field studies of cerebral asymmetry. We present some of the problems associated with ensuring central fixation and argue that objectively monitoring fixation location with an eye-tracking device can provide the only accurate and, therefore, acceptable technique. However, the mere use of this equipment does not overcome all of the problems associated with controlling fixation location, and previous studies have overlooked the importance of providing feedback on fixation accuracy and the role of visual attention. We propose a straightforward method of accommodating both these influences in studies using eyetracking devices to control fixation location.
