Conservation of quantity occurs through recognition that changes in the physical arrangement of a set of items do not change the quantity of items in that set. Rhesus monkeys (Macaca mulatta) were presented with a computerized quantity judgment task. Monkeys were rewarded for selecting the greater quantity of items in one of two horizontal arrays of items on the screen. On some trials, after a correct selection, no reward was given but one of the arrays was manipulated. In some cases, this manipulation involved moving items closer together or farther apart to change the physical arrangement of the array without changing the quantity of items in the array. In other cases, additional items were added to the initially smaller array so that it became quantitatively larger. Monkeys then made another selection from the two rows of items. Monkeys were sensitive to these manipulations, changing their selections when the number of items in the rows changed but not when the arrangement only was changed. Therefore, monkeys responded on the basis of the quantity of items, and they were not distracted by non-quantitative manipulations of the sets.Electronic Supplementary Material Supplementary material is available for this article at 相似文献

Judgments of associative memory (JAM) were indexed by ratings given to pairs of cue and response words. The normed probabilities, p(response|cue), were obtained from free association norms. The ratings were linearly related to the probabilities. The JAM functions were characterized by high intercepts ( approximately 50 on a 100 point scale) and shallow slopes (<0.5). The JAM function generalized across materials and method of rating. The function was not affected by expectancies or semantic similarity. Attempts to alter the function by making alternative responses more available were unsuccessful. A computer simulation model (MINERVA 2) exhibited the linear JAM function and successfully accounted for more complex phenomena (like the joint influence of forward and backward associative strengths on ratings). The shallow JAM slope appears to result from a fundamental lack of discrimination among associative strengths. The high intercept appears to result partly from an independent post-mnemonic source of bias producing over-estimation of association. 相似文献

Invisible Stimuli,Implicit Thresholds: Why Invisibility Judgments
Cannot be Interpreted in Isolation
Thomas Schmidt 《Advances in cognitive psychology / University of Finance and Management in Warsaw》2015,11(2):31-41
Some studies of unconscious cognition rely on judgments of participants stating
that they have “not seen” the critical stimulus (e.g., in a masked-priming
experiment). Trials in which participants gave invisibility judgments are then
treated as those where the critical stimulus was “subliminal” or “unconscious,”
as opposed to trials with higher visibility ratings. Sometimes, only these
trials are further analyzed, for instance, for unconscious priming effects. Here
I argue that this practice requires implicit assumptions about subjective
measures of awareness incompatible with basic models of categorization under
uncertainty (e.g., modern signal-detection and threshold theories). Most
importantly, it ignores the potential effects of response bias. Instead of
taking invisibility judgments literally, they would better be employed in
parametric experiments where stimulus visibility is manipulated systematically,
not accidentally. This would allow studying qualitative and double dissociations
between measures of awareness and of stimulus processing per se. 相似文献

We examined the hypothesis that feeling-of-knowing judgments rely on recollection as well as on familiarity prompted by the cue presentation. A remember-know-no memory procedure was combined with the episodic FOK procedure employing a cue–target pair memory task. The magnitude of FOK judgments and FOK accuracy were examined as a function of recollection, familiarity, or the “no memory” option. Results showed that the proportion of R and K responses was similar. FOK accuracy and magnitude of FOK judgments were higher for R and K responses than for N responses. FOK accuracy related to R and K responses were above chance level, but FOK was not accurate in the “no memory” condition. Finally, both FOK magnitude and FOK accuracy were related more to recollection than to familiarity. These results support the hypothesis that both recollection and familiarity are determinants of the FOK process, although they suggest that recollection has a stronger influence. 相似文献

Not Simply in the Eye of the Beholder: Authenticity as a Product of Candidate Preference and Unfettered Speech 下载免费PDF全文
David R. Pillow Meghan A. Crabtree Manuel J. Galvan Willie J. Hale 《Political psychology》2018,39(4):849-868
Authenticity has emerged over recent decades as a prominent theme in both the press and in political research—and peaked in the 2016 presidential contest that pitted Donald Trump against Hillary Clinton, Bernie Sanders, Marco Rubio, and Ted Cruz. In this context, we attempted to answer the question: How do voters judge a presidential candidate's authenticity? Here we use motivated reasoning and correspondent inference theory as theoretical frameworks to examine how partisan preference combines with perceptions of unfettered speech and strategic impression management to influence voter judgments of a candidate's authenticity. An online survey of 525 respondents demonstrated that individuals' partisan preferences influenced both judgments of a candidate's authenticity and their perceptions of behaviors signifying authenticity (use of unfettered speech versus strategic impression management). These behavioral signals partially mediated the relation between candidate preferences and authenticity judgments. Moreover, voters, given their partisan preferences, differentially weighted candidates' use of unfettered speech and strategic impression management tactics in their judgments of authenticity. Finally, unfiltered/politically incorrect speech was found to have both positive and negative effects on authenticity judgments. Findings further elucidate the nature of authenticity as perceived in others and identify intermediary variables and boundary conditions that influence those perceptions. 相似文献

Researchers have evaluated how broad categories of emotion (i.e. positive and negative) influence judgments of learning (JOLs) relative to neutral items. Specifically, JOLs are typically higher for emotional relative to neutral items. The novel goal of the present research was to evaluate JOLs for fine-grained categories of emotion. Participants studied faces with afraid, angry, sad, or neutral expressions (Experiment 1) and with afraid, angry, or sad expressions (Experiment 2). Participants identified the expressed emotion, made a JOL for each, and completed a recognition test. JOLs were higher for the emotional relative to neutral expressions. However, JOLs were insensitive to the categories of negative emotion. Using a survey design in Experiment 3, participants demonstrated idiosyncratic beliefs about emotion. Some people believed the fine-grained emotions were equally memorable, whereas others believed a specific emotion (e.g. anger) was most memorable. Thus, beliefs about emotion are nuanced, which has important implications for JOL theory. 相似文献

Abstract Previous research suggests that judgments of pain are subject to social influences, including characteristics of the person in pain, the judge, and the social context in which the judgment occurs. In this experiment, eight vignettes describing a person with chronic low back pain were varied as a function of patient ethnicity (Caucasian vs African-American), litigation status (litigant vs non-litigant), and medical evidence (strong vs weak). Participants (N= 116) read vignettes, made attributions of causality for the person's pain and disability, and evaluated the severity of the pain syndrome. Pain and disability were perceived as more legitimate when the person in pain was a non-litigant and when medical evidence was strong. Evaluations of syndrome severity were more extreme when evidence was strong. A three-way interaction indicated that judgments may have been influenced by ethnic stereotypes. These findings substantiate the influence of social variables in judgments of persons with pain. 相似文献

An evolutionary approach to attractiveness judgments emphasises that many human trait preferences exist in order to assist adaptive mate choice. Here we test an adaptive development hypothesis, whereby voice pitch preferences indicating potential mate quality might arise or strengthen significantly during adolescence (when mate choice becomes adaptive). We used a longitudinal study of 250 adolescents to investigate changes in preference for voice pitch, a proposed marker of mate quality. We found significantly stronger preferences for lower-pitched opposite-sex voices in the older age group compared with the younger age group (using different sets of age-matched stimuli), and marginally increased preferences for lower-pitched opposite-sex voices comparing within-participant preferences for the same set of stimuli over the course of 1 year. We also found stability in individual differences in preferences across adolescence: controlling for age, the raters who had stronger preferences than their peers for lower-pitched voices when first tested, retained stronger preferences for lower-pitched voices relative to their peers about 1 year later. Adolescence provides a useful arena for evaluating adaptive hypotheses and testing the cues that might give rise to adaptive behaviour. 相似文献

Children's attributions about story characters in ambiguous and unambiguous social situations were assessed. One hundred and forty-four 6–7-year-olds and 10–11-year-olds heard about actors who slighted a recipient intentionally or for an undetermined reason and then made causal attributions about the events, an emotion attribution about the recipient, and global personality attributions about the actors and recipient. Relations between perceived self-competence and attribution style were also assessed. Participants were more likely to make negative causal attributions in the unambiguous condition and with increasing age. Older girls and younger boys were more likely than other groups to attribute negative emotions to the recipient. Overall, participants perceived recipients positively and actors negatively. Perceived self-competence was positively correlated with actor attributions, although these differed by age and gender. Implications for children's psychosocial adjustment are discussed. 相似文献
