Confidence in Personal Preferences

The first aim of this study was to test the self‐consistency model (SCM) of subjective confidence as it applies to personal preferences. According to SCM, participants presented with a two‐alternative forced‐choice (2AFC) item draw a small sample of representations of the item. Their confidence reflects the extent to which the choice is representative of the population of representations associated with the item, and the likelihood of making that choice on subsequent occasions. The second aim was to use confidence judgment as a clue to the dynamics of online preference construction. Participants were presented with 2AFC items measuring everyday personal preferences. The task was presented five times. In line with SCM, (i) when participants changed their preferences across presentations, they were systematically more confident when they made their more frequent choice; (ii) confidence in a choice in the item's first presentation predicted the likelihood of repeating that choice in subsequent presentations; (iii) despite the idiosyncratic nature of personal preferences, confidence was higher for consensual than for nonconsensual preferences; (iv) when participants predicted the preferences of others, they were also more confident when their predictions agreed with those of others; and (v) the confidence/accuracy correlation for predictions was positive for consensually correct but negative for consensually wrong predictions. These results suggest that confidence in preferences can help separate between the stable and variable contributions to preference construction in terms of the population of representations available in memory and the representations that are accessible at the time of preference solicitation, respectively.

The effect of attractiveness on food sharing preferences in human mating markets

The current study explored how physical attractiveness affects food sharing by studying payment preferences for hypothetical romantic dinner dates (a hypothetical mating market). We analyzed payment preferences, self-rated attractiveness, and rated attractiveness for hypothetical dates in 416 participants. We hypothesized that (1) men would be more likely to prefer to pay than would women, (2) attractive individuals of both sexes would be less willing to pay, and (3) preferences to enter an exchange would be influenced by the attractiveness of prospective partners such that (3a) men would prefer to pay for attractive women, and (3b) women would prefer to be paid for by attractive men. All hypotheses were supported by our results. Individuals with higher self-rated attractiveness were more likely to prefer that their date would pay for the meal, and we found clear sex differences in how the attractiveness of potential dates affected payment preferences. Male participants preferred to pay for dates that had higher facial attractiveness, while female participants preferred that attractive men would pay. Individuals show condition dependent financial preferences consistent with the provisioning hypothesis in this mating market that are adaptive to evaluations of their own quality and that of prospective partners.     

What you don’t know won’t hurt me: Costly (but quiet) exit in dictator games

We used simple economic games to examine pro-social behavior and the lengths that people will take to avoid engaging in it. Over two studies, we found that about one-third of participants were willing to “exit” a $10 dictator game and take $9 instead. The exit option left the receiver nothing, but also ensured that the receiver never knew that a dictator game was to be played. Because most social utility models are defined over monetary outcomes, they cannot explain choosing the ($9, $0) exit outcome over the dominating $10 dictator game, since the game includes outcomes of ($10, $0) and ($9, $1). We also studied exiting using a “private” dictator game. In the private game, the receiver never knew about the game or from where any money was received. Gifts in this game were added innocuously to a payment for a separate task. Almost no dictators exited from the private game, indicating that receivers’ beliefs are the key factor in the decision to exit. When, as in the private game, the receivers’ beliefs and expectations cannot be manipulated by exit, exit is seldom taken. We conclude that giving often reflects a desire not to violate others’ expectations rather than a concern for others’ welfare per se. We discuss the implications of our results for understanding ethical decisions and for testing and modeling social preferences. An adequate specification of social preferences should include “psychological” payoffs that directly incorporate beliefs about actions into the utility function.     

Are economic conditions related to nonnormative life satisfaction development? Evaluating the relative impact of economic conditions,personality, and subjective health

This study examined the relative contribution of psychological and socioeconomic resources to explaining qualitative individual differences in life satisfaction development. We used growth mixture modeling and a cohort‐sequential design to investigate life satisfaction development from ages 25 to 65, in a nationally representative panel (the Socioeconomic Panel). Eighty‐three percent of the participants experienced stability in life satisfaction. In a subgroup of individuals (10%), life satisfaction declined. This subgroup lived under less favorable economic conditions and reported downward moves on an index of socioeconomic status. In another subgroup (7%), life satisfaction was low at age 25 and increased up to age 65. This group was also socioeconomically disadvantaged but scored higher on adaptive personality traits and experienced upward social mobility. Generally, personality traits explained level differences in life satisfaction better than economic conditions. However, economic conditions explained nonnormative life satisfaction development better than generalized control beliefs and the Big Five traits.     

Explaining age differences in temporal working memory

To determine the cognitive mechanisms underlying age differences in temporal working memory (WM), the authors examined the contributions of item memory, associative memory, simple order memory, and multiple item memory, using parallel versions of the delayed-matching-to-sample task. Older adults performed more poorly than younger adults on tests of temporal memory, but there were no age differences in nonassociative item memory, regardless of the amount of information to be learned. In contrast, a combination of associative and simple order memory, both of which were reduced in older adults, completely accounted for age-related declines in temporal memory. The authors conclude that 2 mechanisms may underlie age differences in temporal WM, namely, a generalized decline in associative ability and a specific difficulty with order information.     

An improved spatial span test of visuospatial memory

In the widely used Corsi Block Test and Wechsler Spatial Span Tests, participants must reproduce sequences of blocks in the order touched by the examiner until two trials are missed at the same sequence length. The examiner records either the maximum number of blocks correctly reported or the total number of correct lists. Here, we describe a computerized spatial span test (C-SST) that uses psychophysical procedures to quantify visuospatial mean span (MnS) with sub-digit precision. Results from 187 participants ranging in age from 18 to 82 years showed that accuracy declined gradually with list length around the MnS (by ～30% per item). Simulation studies revealed high variance and biases in CBT and Wechsler measures, and demonstrated that the C-SST provided the most accurate estimate of true span (i.e., the sequence length producing 50% correct). MnS declined more rapidly with age than mean digit span (MnDS) measured in the same participants. Response times correlated with both MnS and MnDS scores. Error analysis showed that omission and transposition errors predominated, with weaker primacy and recency effects in spatial span than digit span testing. The C-SST improves the precision of spatial span testing and reveals significant differences between visuospatial and verbal working memory.     

Assessing the value of choice in a token system

Responding of 4 children was assessed under conditions in which (a) no programmed contingencies were arranged for target behavior, (b) responding produced tokens that could be exchanged for a single highly preferred edible item, and (c) responding produced a token that could be exchanged for a variety of preferred edible items. After assessing the effects of these contingencies, the preferences of 3 participants were assessed using a concurrent-chains schedule. Preference for the opportunity to choose from the same or qualitatively different edible items varied across participants, and findings were generally consistent with those of Tiger, Hanley, and Hernandez (2006).     

Age differences in item manipulation span: the case of letter-number sequencing

The authors report 2 experiments in which they examined age differences in working memory tasks involving complex item manipulation (i.e., letter-number sequencing). In Experiment 1, age differences on tasks involving item manipulation were not greater than age differences on tasks requiring recall of items in the order in which they appeared, suggesting that older adults do not have difficulty with item manipulation per se. In Experiment 2, slower presentation rates increased age differences in item manipulation spans, although age differences at the fastest rate may be attributed to differences in strategy use. In both experiments, age differences were largest when participants were most likely to be remembering familiar sequences, suggesting that older adults may have difficulties dampening the representations of such sequences once they are activated.     

Gender Differences in Leadership Aspirations and Job and Life Attribute Preferences among U.S. Undergraduate Students

The purpose of the present study was to examine gender differences in constructs associated with leadership aspirations in a sample of 467 undergraduate students because these might contribute to the gender gap in leadership attainment. The results demonstrated that female participants perceived themselves as having less leadership ability than male participants, and viewed their attainment of leadership roles as less likely than male participants did, which could reflect anticipated discrimination. Female participants reported less interest than male participants in elite leadership positions (e.g., CEO, senator), and associated positive characteristics with such roles less than male participants. They were also less likely than male participants to indicate a willingness to accept a promotion that would require them to sacrifice enjoyable work. Male and female participants ranked the importance of a variety of job and life attribute preferences similarly, though female participants emphasized the importance of life attribute preferences (e.g., family, good health), whereas male participants emphasized the importance of job attribute preferences (e.g., high salary). Finally, male participants were more likely than female participants to expect and prefer that they would out-earn their future spouses. These results highlight the need for greater consideration of how young women’s and men’s leadership aspirations and job/life preferences contribute to the gender gap in leadership attainment.     

Young and older adults' beliefs about effective ways to mitigate age-related memory decline

This study investigated whether young and older adults vary in their beliefs about the impact of various mitigating factors on age-related memory decline. Eighty young (ages 18-23) and 80 older (ages 60-82) participants reported their beliefs about their own memory abilities and the strategies that they use in their everyday lives to attempt to control their memory. Participants also reported their beliefs about memory change with age for hypothetical target individuals who were described as using (or not using) various means to mitigate memory decline. There were no age differences in personal beliefs about control over current or future memory ability. However, the two age groups differed in the types of strategies they used in their everyday life to control their memory. Young adults were more likely to use internal memory strategies, whereas older adults were more likely to focus on cognitive exercise and maintaining physical health as ways to optimize their memory ability. There were no age differences in rated memory change across the life span in hypothetical individuals. Both young and older adults perceived strategies related to improving physical and cognitive health as effective means of mitigating memory loss with age, whereas internal memory strategies were perceived as less effective means for controlling age-related memory decline.     

Preference for reinforcers under progressive- and fixed-ratio schedules: a comparison of single and concurrent arrangements

Progressive-ratio (PR) schedules were used to identify the break point (i.e., the last schedule value completed) for 2 reinforcers under single and concurrent schedules. After the respective break points were established, the same reinforcers were presented under concurrent fixed-ratio (FR) schedules that were yoked to the break points obtained with the PR schedules. Results suggested that the participants responded more for the high-preference item than for the low-preference item, regardless of the presentation arrangement (single or concurrent presentations). This pattern of responding was maintained when the reinforcers were presented under dissimilar FR schedules. The results suggest that responding for differentially preferred stimuli may vary as a function of differences in schedule requirements.     

Effects of escalating and descending schedules of incentives on cigarette smoking in smokers without plans to quit

Contingent incentives can reduce substance abuse. Escalating payment schedules, which begin with a small incentive magnitude and progressively increase with meeting the contingency, increase smoking abstinence. Likewise, descending payment schedules can increase cocaine abstinence. The current experiment enrolled smokers without plans to quit in the next 6 months and compared escalating and descending payments schedules over 15 visits. In the larger incentive condition (LI, n = 39), the largest possible incentive was $100, and in the smaller incentive condition (SI, n = 18), the largest possible incentive was $32. In both conditions, more participants in the descending groups initiated abstinence. A higher proportion of participants in both the escalating and descending groups initiated abstinence in the LI than in the SI. Although participants in the descending groups had more abstinent visits during the first five contingent visits than those in the escalating groups, these differences were not maintained.     

Developmental change in the relation between simple and complex spans: a meta-analysis

In the present meta-analysis the effects of developmental level on the correlation between simple and complex span tasks were investigated. Simple span-complex span correlation coefficients presented in 52 independent samples (7,060 participants) were regressed on a variable representing mean age of sample (range: 4.96-22.80 years), using analyses adapted for meta-analytic purposes. The results showed strong positive relations between mean age of sample and simple span-complex span correlation coefficients, suggesting that the relation between simple and complex span tasks became stronger with increasing age. These results could not be accounted for by study-related differences in measurement reliability, restricted range, or sample size. A new theoretical account explaining these findings is outlined.     

Effects of Age,Domain, and Processing Demands on Memory Span: Evidence for Differential Decline

Analysis of cross-sectional data from the normative sample of the Wechsler Memory Scale - Third Edition (WMS-III) revealed different patterns of age-related differences in memory span measures depending on the type of memory item, processing demands, and the age of the older adult group. Regression of memory span on age revealed that the slope for Spatial Span raw scores was significantly more negative than the slope for Digit Span raw scores. There was no significant difference, however, either between the slopes for forward and backward Digit Span or between the slopes for forward and backward Spatial Span. Regression of Letter-Number Sequencing raw scores on age showed a distinctive, curvilinear pattern. Taken together, the present findings suggest that at least two mechanisms are involved in age-related differences in memory span. One mechanism, associated with a relatively linear decrease in memory span as a function of age, may differentially affect the storage of different types of information (e.g., sequences of digits vs. spatial locations). The other mechanism, evidenced by the curvilinear trend in Letter-Number Sequencing scores, may be tentatively attributed to a decline in executive aspects of working memory that becomes increasingly pronounced with age.     

Committing memory errors with high confidence: older adults do but children don't

We investigated lifespan differences of confidence calibration in episodic memory, particularly the susceptibility to high-confidence errors within samples of children, teenagers, younger adults, and older adults. Using an associative recognition memory paradigm, we drew a direct link between older adults' associative deficit and high-confidence errors. We predicted that only older adults would show high-confidence error even though their memory performance was at a similar level to that of children. Participants of all ages showed higher confidence following correct responses compared to incorrect responses, demonstrating the ability to calibrate subjective confidence in relation to memory accuracy. However, older adults were disproportionately more likely to indicate high confidence following erroneously remembered word pairs than participants of the other three age groups. Results are discussed in relation to the misrecollection account of high-confidence errors and ageing-related decline in hippocampus-dependent episodic memory functions.     

How to Study Choice-Induced Attitude Change: Strategies for Fixing the Free-Choice Paradigm

The theory of cognitive dissonance has been among the most influential theories in social psychology for the last 50 years. Support for the theory has come primarily from three experimental paradigms: free-choice, induced compliance, and effort justification. Recently, Chen and Risen (2010, Journal of Personality and Social Psychology, 99 , 573–594) have argued that although the free-choice paradigm reliably finds a ‘spreading of alternatives’ (i.e., after making a choice, participants’ evaluations of the chosen item improve and evaluations of the rejected item decline), these results cannot be interpreted as evidence for dissonance reduction or attitude change. Unlike the other dissonance paradigms, participants ‘self-select’ how they are treated in the free-choice paradigm, making it impossible to know whether spreading is because of the choice process or the information that is revealed about participants’ existing preferences. The current paper has two goals. First, we will describe the criticism developed by Chen and Risen (2010) and situate the criticism within the broader study of dissonance. Second, we will offer four suggestions for how researchers can isolate the effect of the choice process and properly test for choice-induced attitude change in the free-choice paradigm.     

Self-generation amplifies the errorless learning effect in healthy older adults when transfer appropriate processing conditions are met

ABSTRACT

Older adults have considerable impairment in associative recognition despite minimal age differences in item recognition. The magnitude of this associative deficit varies by type of stimuli, strategy utilization, and other mediators and moderators (Old &; Naveh-Benjamin, 2008 Old, S. R., &; Naveh-Benjamin, M. (2008). Differential effects of age on item and associative measures of memory: A meta-analysis. Psychology and Aging, 23, 104–118. doi: 10.1037/0882-7974.23.1.104[Crossref], [PubMed], [Web of Science ®] , [Google Scholar], Psychology and Aging, 23, 104–118). Name pair stimuli have not been used to test the associative deficit hypothesis (ADH), although tests using name–face stimuli support the ADH. Additionally, metacognitive awareness of the ADH has not been investigated. We tested the ADH with word and name pair stimuli, and predicted that age-related associative deficits would be larger for words than names because names, unlike most common nouns, lack certain semantic properties that could be used to bind pairs of names together. Results supported the ADH for words but not names: Younger and older adults recognized equivalently fewer names on the associative test relative to the item test. As predicted, self-efficacy was higher for younger than older adults. Surprisingly, self-efficacy for the associative test was higher than for the item test but post-test estimates of performance success (postdictions) were higher for the item test than for the associative test, suggesting sensitivity by participants to different task demands in the item and associative tests following recognition attempts. Metacognitive accuracy was better for words than names and for the item test than associative test, and equivalent between age groups. Overall, participants overestimated their name recognition abilities. Our findings extend support for the ADH to a conceptually important and ecologically valid domain (names) and provide new data on metacognitive aspects of the ADH.     

The effects of control of resources on magnitudes of sex differences in human mate preferences

We tested the hypothesis that magnitudes of sex differences in human mate preferences would be inversely related to control of resources. Specifically, we predicted that the ideal partner age, maximum and minimum partner ages tolerated and preferences for "physical attractiveness" over "good financial prospects" of female participants would approach parity with that of men with increasing control of resources. In a sample of 3770 participants recruited via an online survey, the magnitudes of sex differences in age preferences increased with resource control whereas the sex difference in preferences for "physical attractiveness" over "good financial prospects" disappeared when resource control was high. Results are inconsistent, and are discussed in the context of adaptive tradeoff and biosocial models of sex differences in human mate preferences.     

The development of memory efficiency and value-directed remembering across the life span: a cross-sectional study of memory and selectivity

Although attentional control and memory change considerably across the life span, no research has examined how the ability to strategically remember important information (i.e., value-directed remembering) changes from childhood to old age. The present study examined this in different age groups across the life span (N = 320, 5-96 years old). A selectivity task was used in which participants were asked to study and recall items worth different point values in order to maximize their point score. This procedure allowed for measures of memory quantity/capacity (number of words recalled) and memory efficiency/selectivity (the recall of high-value items relative to low-value items). Age-related differences were found for memory capacity, as young adults recalled more words than the other groups. However, in terms of selectivity, younger and older adults were more selective than adolescents and children. The dissociation between these measures across the life span illustrates important age-related differences in terms of memory capacity and the ability to selectively remember high-value information.
