Job-content Perceptions, Performance–reward Expectancies, and Absenteeism among Low-wage Public-sector Clerical Employees

This study explored relations of job-content perceptions (i.e., skill variety and task significance), and performance–reward expectancies, with absenteeism among 134 low-wage public-sector clerical employees. Results indicated that those employees who perceived limited performance–reward expectancies (i.e., lower instrumentality), and who considered their jobs to be either higher on skill variety or task significance, were likely to be absent more often. Moreover, the link between skill variety and absenteeism was moderated by instrumentality in a manner suggesting that respondents may have utilized absenteeism as a means of compensating for perceived workplace contributions not extrinsically rewarded. These findings further suggest that employees in occupational settings for which performance-related extrinsic rewards are less available may not respond to favorable job-content perceptions in the positive manner generally predicted by job characteristics theory.     

A systematic overview of methods,their limitations,and their opportunities to investigate inattentional blindness

During the past two decades, the interest in investigating the phenomenon of inattentional blindness strongly increased and resulted in a fraying of paradigms investigating this specific failure of awareness. We reviewed 129 full‐text articles containing 219 experiments for their design and methods to create awareness for the growing variety of inattentional blindness paradigms. Also, we promote a deliberate use of future paradigms (proposedly based on their functionality and representativeness) to improve the transferability of research findings to the real world. In general, we argue that paradigms should be well‐chosen based on the respective purpose, as the concept of inattentional blindness represents most likely several subtypes with different underlying mechanisms rather than a single phenomenon. Finally, we propose to include expectancy as a continuous variable into the definition of inattentional blindness rather than using it as an exclusion criterion.     

Evaluating the contributions of task expectancy in the testing and guessing benefits on recognition memory

Recently, we have shown that two types of initial testing (recall of a list or guessing of critical items repeated over 12 study/test cycles) improved final recognition of related and unrelated word lists relative to restudy. These benefits were eliminated, however, when test instructions were manipulated within subjects and presented after study of each list, procedures designed to minimise expectancy of a specific type of upcoming test [Huff, Balota, & Hutchison, 2016. The costs and benefits of testing and guessing on recognition memory. Journal of Experimental Psychology: Learning, Memory, and Cognition, 42, 1559–1572. doi:10.1037/xlm0000269], suggesting that testing and guessing effects may be influenced by encoding strategies specific for the type of upcoming task. We follow-up these experiments by examining test-expectancy processes in guessing and testing. Testing and guessing benefits over restudy were not found when test instructions were presented either after (Experiment 1) or before (Experiment 2) a single study/task cycle was completed, nor were benefits found when instructions were presented before study/task cycles and the task was repeated three times (Experiment 3). Testing and guessing benefits emerged only when instructions were presented before a study/task cycle and the task was repeated six times (Experiments 4A and 4B). These experiments demonstrate that initial testing and guessing can produce memory benefits in recognition, but only following substantial task repetitions which likely promote task-expectancy processes.     

Vibrotactile timing: Are vibrotactile judgements of duration affected by repetitive stimulation?

Timing in the vibrotactile modality was explored. Previous research has shown that repetitive auditory stimulation (in the form of click-trains) and visual stimulation (in the form of flickers) can alter duration judgements in a manner consistent with a “speeding up” of an internal clock. In Experiments 1 and 2 we investigated whether repetitive vibrotactile stimulation in the form of vibration trains would also alter duration judgements of either vibrotactile stimuli or visual stimuli. Participants gave verbal estimates of the duration of vibrotactile and visual stimuli that were preceded either by five seconds of 5-Hz vibration trains, or, by a five-second period of no vibrotactile stimulation, the end of which was signalled by a single vibration pulse (control condition). The results showed that durations were overestimated in the vibrotactile train conditions relative to the control condition; however, the effects were not multiplicative (did not increase with increasing stimulus duration) and as such were not consistent with a speeding up of the internal clock, but rather with an additive attentional effect. An additional finding was that the slope of the vibrotactile psychometric (control condition) function was not significantly different from that of the visual (control condition) function, which replicates a finding from a previous cross-modal comparison of timing.     

Political support for self-determination,wealth, and national subjective well-being

The present paper explored the relation of wealth and support for self-determination to national subjective well-being (SWB). Support for self-determination was considered from both a political and cultural values standpoint. The results confirmed associations between wealth, support for self-determination, and well-being in a large sample of countries. Importantly, political and cultural value supports for self-determination remained significantly associated with national well-being (as measured by happiness reports and life expectancy) even after controlling for national differences in wealth.

Drug effects: Agonistic and antagonistic processes

The research presented here has shown that tolerance to drugs can be accelerated by conditioning processes. Placebo effects may be considered the opposite of tolerance, and we have shown that placebo effects may be objectively recorded by physiological measures (electromyography, skin conductance responses, and event‐related potentials), as well as by behavioral and subjective methods. The placebo response, or more precisely, the expectation of drug effects, can add to the effect of the drug. Drug antagonistic expectations can also reverse the effect of the drug. There is some evidence that placebo effects are strongest when expectations are reinforced by administration of an active drug. Expectations have graded effects and may affect symptoms to a smaller or larger degree. Although drug effects can be considered stimuli, the investigation of the role of classical conditioning in drug use and drug effects involves special issues that must be carefully considered.     

The Effect of Goal Difficulty on Escalation of Commitment

Escalation of commitment to a failing course of action is a problem in behavioral decision making that occurs across a wide range of social contexts. In this research, we show that examining escalation of commitment from a goal setting theory perspective provides fresh insights into how goal difficulty influences escalation of commitment. Specifically, through a series of two experiments, we found a curvilinear relationship between goal difficulty and post‐feedback goal commitment, which was mediated by valence and expectancy associated with goal attainment. In turn, it is commitment to goals that leads individuals to continue a previous course of action despite negative feedback. Copyright © 2014 John Wiley & Sons, Ltd.

Psychometric Assessment of the Comprehensive Effects of Alcohol Questionnaire: Comparing a Brief Version to the Original Full Scale

The current set of studies compared the psychometric properties of the original Comprehensive Effects of Alcohol Questionnaire (CEOA) to a 15-item version (B-CEOA) in a nonclinical undergraduate sample (N = 581), and attempted to replicate and extend the B-CEOA findings in an undergraduate sample referred to an alcohol intervention (N = 734). Psychometric assessment included construct validity, internal consistency, and concurrent validity, using both positive and negative expectancy items in all analyses. Results provided further support for the empirical validity of the original CEOA, and provided support for the use of the B-CEOA despite the reduction in the number of items. The B-CEOA factor structures obtained using exploratory and confirmatory techniques provided support for a 4-factor structure of expectancies and 3-factor structure of valuations. Findings reveal potential problems with positive and negative expectancy items. Trade-offs regarding factor structure, internal consistency, and administration time should be considered in using the B-CEOA vs. the CEOA.
