The First Twenty Years of the Will and the Ways: An Examination of Score Reliability Distribution on Snyder’s Dispositional Hope Scale

C. R. Snyder has established hope theory as an important contributor to positive psychology. As the empirical evidence continues to grow, hope researchers need to have confidence that their measures will produce reliable scores. This study presents a reliability generalization on both the internal consistency and test–retest reliability estimates from Snyder’s dispositional hope scale. While over 300 published works were found to have cited the target article 74 present internal consistency scores and 17 reported scores for test–retest reliability. The results of the reliability generalization suggest support for the score reliabilities produced by the dispositional hope scale. However, internal consistency was higher for studies using the eight-item response format (α = 0.82) compared to those using the four-item response format (α = 0.77). Additionally, the test–retest score reliability was high 0.80 with no statistically significant differences by response format. Findings also demonstrated that score reliability estimates were not significantly influenced by the coded sample characteristics.     

Contextual Pavlovian conditioning in the crab Chasmagnathus

In contextual conditioning, a complex pattern of information is processed to associate the characteristics of a particular place with incentive or aversive reinforcements. This type of learning has been widely studied in mammals, but studies of other taxa are scarce. The context-signal memory (CSM) paradigm of the crab Chasmagnathus has been extensively used as a model of learning and memory. Although initially interpreted as habituation, some characteristics of contextual conditioning have been described. However, no anticipatory response has been detected for animals exposed to the training context. Thus, CSM could be interpreted either as an associative habituation or as contextual conditioning that occurs without a context-evoked anticipatory response. Here, we describe a training protocol developed for contextual Pavlovian conditioning (CPC). For each training trial, the context (conditioned stimulus, CS) was discretely presented and finished together with the unconditioned stimulus (US). In agreement with the CSM paradigm, a robust freezing response was acquired during the 15 training trials, and clear retention was found when tested with the US presentation after short (2 and 4 h) and long (1–4 days) delays. This CPC memory showed forward but not simultaneous presentation conditioning and was context specific and protein synthesis dependent. Additionally, a weak CPC memory was enhanced during consolidation. One day after training, CPC was extinguished by repeated CS presentation, while one presentation induced a memory labilisation–reconsolidation process. Finally, we found an anticipatory conditioned response (CR) during the CS presentation for both short-term (4 h) and long-term memory (24 h). These findings support the conditioning nature of the new paradigm.     

Subjective Difficulty of Movements With Ongoing Visual Control

Objective difficulty of a single-component visually controlled movement may be defined by Fitts's (1954) Index of Difficulty, which is a measure of difficulty in the sense that movement time is linearly related to the objective measure. For movements that have multiple components, it becomes difficult to determine an objective measure of task difficulty due to unknown interactions between components of the movement and interactions with other factors. Thus, it may be necessary to use indirect methods for allocating a measure of task difficulty. The purpose of the study was to determine whether participants could validly construct a subjective measure of the movement difficulty and whether this measure was related to the known objective measure of difficulty. Experiments showed that for single-component movements, there was a close relationship between measures of subjective and objective difficulty. With two-component visually controlled movements it was found that subjective difficulty could be related to objective difficulty, but not as simply as for single-component tasks.     

Performance on a Following Tracking Task (Modified Sam Two-Hand Coordination Test) as a Function of Radius of Control Cranks

The influence of two deindividuating variables, altered responsibility and coaction in groups, on one's tendency to deliver noxious or helpful stimulation impulsively and in a cyclical pattern to a target person was investigated in a laboratory experiment with use of 96 male and female junior college students. Analysis of variance revealed that, as hypothesized, Ss who coacted in groups of three and who had the responsibility for their behavior removed delivered noxious (but not helpful) stimuli more impulsively than Ss who worked alone and were made to feel responsible (p < .01). Ss responded in a more cyclical pattern when delivering aversive tones than when delivering facilitating tones (p < .005). A marginally significant finding was that Ss in groups responded in a more cyclical pattern than Ss alone only when the response was seen as aversive. It was concluded that the probability of impulsive and cyclical aggression may be increased by altered responsibility and coaction.     

Maturational Changes in Canadian Adolescents' Cognitive Attitudinal Structure Concerning Marijuana

Thirty-four items concerning marijuana use were administered three times to a cohort of Canadian high school students between Grades 11 and 13, in 1977 (n = 439), 1978 (n = 419), and 1979 (n = 167). These items were designed to measure four distinct constructs: attitude, perceived peer approval or disapproval, concern about risks, and symbolic protest against conventional society. A cross-sectional factor analysis of the Grade 13 data supported the hypothesized factor structure, as had earlier work with college students. However, analogous analyses on the Grade 11 and Grade 12 data contradicted the hypothesized factor structure. Most notably, separate factors for positive and negative attitude appeared in the Grade 11 and 12 analyses. The data were interpreted primarily in terms of maturational changes, largely through elimination of alternative interpretations by internal analyses and previous findings. Implications were discussed for adolescent cognitive-attitudinal development, attitude theory, and analysis of panel data.     

ideology and the stagnation of aoda treatment modalities in america

The disease model of alcoholism was adopted by the American Medical Assoication in 1956, and the intervening 47 years have seen the development of increasingly varied and sophisticated types of evidence for the biological sources of addiction to Alcohol and other drugs of abuse (AODA) . However, a synthesis of 12-step treatment with a confrontational and moralistic version of cognitive psychology remains the modal approach to AODA treatment, despite its inability to even engage many addicts. Simultaneously, the growing evidence for therapies that teach self-regulation of biopsychological processes, which treat clients supportively while encouraging their recognition of the problems and building their desire to change, has been largely ignored by practitioners. The epitome of this self-regulation approach, neurofeedback therapy, has been all but ignored despite reports of high success rates. This paper examines the confluence historical economic and ideological factors that maintain this divergence between knowledge and practice from the perspective of Gusfield's notion of moral passage based on deviant labels.     

Testing a Theoretical Model Based on Social Cognitive Theory for Media Influences on Suicidal Ideation: Results from a Panel Study

The influence of media representations of suicides on the subsequent increase of suicide rate has been researched for decades. Yet the underlying psychological mechanism of such media influences on individual's suicidality remains uncertain. Based on the conceptual framework of social cognitive theory, this article discusses the operationalization of media influences on suicidal ideation by using a psychometric approach. It then develops and tests a theoretical model to explain the mechanism of media influences on suicidal ideation. A two-wave panel study with a randomized population sample was carried out in the Hong Kong SAR, China with the results indicating that the proposed operationalization closely fit the data collected and empirically supported the theoretical model. Reciprocal associations between prior suicidal ideation and processes of media influences were also confirmed. The results also tested the factorial invariance across age groups and different pre-existing levels of suicidal ideation. This study reports the first individual-level finding on the theoretical relationship between media influences and suicidal ideation, as well as the first psychometrically validated operationalization of media influences on suicidal ideation.

Happy Family Kitchen: Behavioral Outcomes of a Brief Community-Based Family Intervention in Hong Kong

Positive psychology interventions commonly involve behavioral exercises to improve psychosocial well-being. Intervention effect on behavior is unclear. The Happy Family Kitchen project, one of the community-based brief intervention projects under The FAMILY: A Jockey Club Initiative for a Harmonious Society, was conducted in Hong Kong to develop and evaluate the effectiveness of a positive psychology family intervention. We have previously reported positive intervention effects on family communication, family well-being, and subjective happiness. This paper aims to explore the effectiveness of the intervention on behavioral outcomes and their associations with psychosocial well-being. A total of 23 social service units organized and conducted intervention programs for 1419 individuals from 612 families in Hong Kong. Each intervention was developed with emphasis on one of five positive psychology themes: gratitude, flow, happiness, health, and savoring. Intervention outcomes were assessed at pre-intervention, immediate post-intervention, and 6 weeks and 12 weeks post-intervention. Results showed that family communication time and frequency of meal preparation with family members increased with sustainable small effects up to 12 weeks. Theme-specific behavior change was observed in the gratitude, flow, and happiness interventions, respectively. Family communication time, frequency of eating with family members, and theme-specific behaviors, including gratitude, flow, happiness behavior, health attitude, and health behavior, were positively associated with psychosocial well-being. Qualitative data provided additional evidence of effectiveness with in-depth insights into behavior change. The positive associations between target behaviors and well-being suggest that improvements in well-being as a function of the intervention may be associated with behavior change.     

Cross‐Linguistic Differences in Digit Memory Span

This study investigated whether the better performance of the Chinese in digit memory span tasks was due only to the shorter pronunciation duration of Chinese digit names, or to enhanced visuospatial sketchpad abilities, or to both. Results of the experiment showed that the Chinese outperformed their Malay counterparts in digit memory span tasks because Chinese digit names had shorter pronunciation durations than Malay digit names and not because the Chinese had better visuospatial sketchpad abilities than the Malays. The results thus support Baddeley's phonological loop hypothesis as an account for cross‐linguistic differences in digit memory spans. Because memory traces are subject to decay and the phonological store is temporally limited, the shorter the pronunciation duration of digit names in a language, the more digits one can rehearse within a limited time period, and therefore the larger is one's short‐term digit span in that language.
