Life History and System Justification: Higher Individual Fertility and Lower Provincial Life Expectancy Correlate With Stronger Progovernment Attitudes in China

System justification theory posits that people sometimes legitimize current social arrangements at their own cost. Indeed, research showed that lower socioeconomic status (SES) correlates with stronger progovernment attitudes, but this correlation does not appear reliable. This research proposes a different class of correlates of progovernment attitudes drawing on life history (LH) theory. People who pursue a faster LH strategy (e.g., reproducing earlier and in larger quantities) should be more progovernment because their lower resource‐accruing potential makes them more dependent on government support (e.g., public services and social welfare) to raise a large family. Supporting this hypothesis, Chinese respondents’ individual fertility positively correlated with confidence in government (Study 1) and partially mediated the negative correlation between provincial life expectancy and support of censoring government criticisms (Study 2). These findings suggest an alternative explanation to some of the correlations between SES and progovernment attitudes, provide a new mechanism of system justification, and add to the growing body of work on LH strategy and political psychology.

Stimulus control and associative learning.

Interest in operant research on stimulus control has declined at the same time that much interest has burgeoned in nonoperant areas. Several examples of this shift toward traditional learning theory are considered, all of which have sponsored theoretical approaches that attempt to characterize the underlying associative units. These theoretical approaches are defended on the grounds that they have generated a deeper understanding of a variety of often puzzling phenomena. My projection is that future research will be determined even more strongly by theories about the structure of associations. Particular issues for which such discussion will have major impact include (1) whether conditional stimulus control is qualitatively different than simpler forms of stimulus control, (2) whether stimulus control is organized hierarchically, and (3) the origin of categories of stimulus equivalence.     

Time, trace, memory

Objections to a trace hypothesis for interval timing do not apply to the multiple-time-scale (MTS) theory, which incorporates a dynamic trace tuned by the system history and can easily accommodate interval timing over a 1,000:1 range. The MTS model can also account for Weber's law as well as systematic deviations from it. Contrary to our critics, we contend that patterns of variance in interval timing experiments are not fully described by scalar expectancy theory, and that attempting to understand timing by assigning variance to different elements of a flexible model that lacks inductive support is a flawed strategy, because the attempt may be successful even if the model is wrong. We further argue that biological plausibility is an unreliable guide to the development of behavioral theory, that prediction is not the same as test, that induction should precede deduction, and that a rat is not a clock.     

Mindfulness or expectancy? The label of mindfulness leads to expectancy effects

The increasing popularity of mindfulness practices has seen an accompanying growth in research that includes the development of several self-report mindfulness measures. However, while caution has been recommended in the use of these self-reports, there has been little direct assessment of their susceptibility to expectancy effects. This research aimed at understanding whether expectancy effects exist for self-reported mindfulness measures (Study 1; n = 60), and how expectancy effects might manifest in relation to positive and negative expectancy (Study 2; n = 60). The first study manipulated whether (i) the task (jigsaws) was labelled as “mindfulness,” and (ii) whether “authentic” mindfulness instructions were given. Given any increases in self-reported mindfulness might potentially occur due to engaging in the mindful and attentionally demanding task, the second study manipulated whether the introduction placed mindfulness in a positive or negative context. A pre-/post-test design was employed using the Five Facet Mindfulness Questionnaire and Applied Mindfulness Process Scale self-report measures for mindfulness and the Perceived Stress Scale for well-being. The findings revealed expectancy effects for simply using the term mindfulness and that the direction of effects could be manipulated. This research suggests that researchers need to be cautious in evaluating self-reports of mindfulness practice due to expectancy effects, especially in the context of brief interventions without objective measures.

Assessing preference for reinforcers using demand curves, work-rate functions, and expansion paths

Much research has focused on the effects of environmental variability on foraging decisions. However, the general pattern of preference for variability in delay to reward and aversion to variability in amount of reward remains unexplained a either a mechanistic or a functional level. Starlings' preferences between a fixed and a variable option were studied in two treatments, A and D. The fixed option was the same in both treatments (20-s fixed-interval delay, five units food). In Treatment A the variable option gave two equiprobable amounts of food (20-s delay, three or seven units) and in D it gave two equiprobable delays to food (2.5-s or 60.5-s delays, five units). In both treatments the programmed ratio [amount/(intertrial interval+latency+delay)] in the fixed option equaled the arithmetic mean of the two possible ratios in the variable option (ITI = 40 s, latency = 1 s). The variable option was strongly preferred in Treatment D and was weakly avoided in Treatment A. These results are discussed in the light of two theoretical models, a form of constrained rate maximization and a version of scalar expectancy theory. The latter accommodates more of the data and is based on independently verifiable assumptions, including Weber's law.     

Molar versus local reinforcement probability as determinants of stimulus value.

During one component of a multiple schedule, pigeons were trained on a discrete-trial concurrent variable-interval variable-interval schedule in which one alternative had a high scheduled rate of reinforcement and the other a low scheduled rate of reinforcement. When the choice proportion between the alternatives matched their respective relative reinforcement frequencies, the obtained probabilities of reinforcement (reinforcer per peck) were approximately equal. In alternate components of the multiple schedule, a single response alternative was presented with an intermediate scheduled rate of reinforcement. During probe trials, each alternative of the concurrent schedule was paired with the constant alternative. The stimulus correlated with the high reinforcement rate was preferred over that with the intermediate rate, whereas the stimulus correlated with the intermediate rate of reinforcement was preferred over that correlated with the low rate of reinforcement. Preference on probe tests was thus determined by the scheduled rate of reinforcement. Other subjects were presented all three alternatives individually, but with a distribution of trial frequency and reinforcement probability similar to that produced by the choice patterns of the original subjects. Here, preferences on probe tests were determined by the obtained probabilities of reinforcement. Comparison of the two sets of results indicates that the availability of a choice alternative, even when not responded to, affects the preference for that alternative. The results imply that models of choice that invoke only obtained probability of reinforcement as the controlling variable (e.g., melioration) are inadequate.     

Act local but don’t think too global: The impact of ecological goal level on behavior

ABSTRACT

Growing awareness of humanity’s impact on the environment raises the question of how best to encourage pro-environmental actions. Numerous campaigns have been created to convince people to adopt environmentally friendly everyday behaviors, with varying success. The difficulty may be due, at least in part, to the huge gap between these small individual actions and the high-level goals, such as “saving the planet,” often used as incentives. We tested this hypothesis via four experiments. Studies 1 and 2 showed that high-level goals were less effective than low-level goals in promoting paper- and energy-saving behaviors. Study 3 showed that high-level goals engender lower perceived outcome expectancy and higher perception of cumulative effort. Study 4 showed that outcome expectancy mediates the direct effect of goal level on intention.
