Two compelling principles, the Reasonable Range Principle and the Preservation of Irrelevant Evidence Principle, are necessary conditions that any response to peer disagreements ought to abide by. The Reasonable Range Principle maintains that a resolution to a peer disagreement should not fall outside the range of views expressed by the peers in their dispute, whereas the Preservation of Irrelevant Evidence (PIE) Principle maintains that a resolution strategy should be able to preserve unanimous judgments of evidential irrelevance among the peers. No standard Bayesian resolution strategy satisfies the PIE Principle, however, and we give a loss aversion argument in support of PIE and against Bayes. The theory of imprecise probability allows one to satisfy both principles, and we introduce the notion of a set‐based credal judgment to frame and address a range of subtle issues that arise in peer disagreements. 相似文献

The spatial-numerical association of response codes (SNARC) effect is the tendency for humans to respond faster to relatively larger numbers on the left or right (or with the left or right hand) and faster to relatively smaller numbers on the other side. This effect seems to occur due to a spatial representation of magnitude either in occurrence with a number line (wherein participants respond to relatively larger numbers faster on the right), other representations such as clock faces (responses are reversed from number lines), or culturally specific reading directions, begging the question as to whether the effect may be limited to humans. Given that a SNARC effect has emerged via a quantity judgement task in Western lowland gorillas and orangutans (Gazes et al., Cog 168:312–319, 2017), we examined patterns of response on a quantity discrimination task in American black bears, Western lowland gorillas, and humans for evidence of a SNARC effect. We found limited evidence for SNARC effect in American black bears and Western lowland gorillas. Furthermore, humans were inconsistent in direction and strength of effects, emphasizing the importance of standardizing methodology and analyses when comparing SNARC effects between species. These data reveal the importance of collecting data with humans in analogous procedures when testing nonhumans for effects assumed to bepresent in humans. 相似文献

Restricted stimulus control refers to discrimination learning with atypical limitations in the range of controlling stimuli or stimulus features. In the study reported here, 4 normally capable individuals and 10 individuals with intellectual disabilities (ID) performed two-sample delayed matching to sample. Sample-stimulus observing was recorded with an eye-tracking apparatus. High accuracy scores indicated stimulus control by both sample stimuli for the 4 nondisabled participants and 4 participants with ID, and eye tracking data showed reliable observing of all stimuli. Intermediate accuracy scores indicated restricted stimulus control for the remaining 6 participants. Their eye-tracking data showed that errors were related to failures to observe sample stimuli and relatively brief observing durations. Five of these participants were then given interventions designed to improve observing behavior. For 4 participants, the interventions resulted initially in elimination of observing failures, increased observing durations, and increased accuracy. For 2 of these participants, contingencies sufficient to maintain adequate observing were not always sufficient to maintain high accuracy; subsequent procedure modifications restored it, however. For the 5th participant, initial improvements in observing were not accompanied by improved accuracy, an apparent instance of observing without attending; accuracy improved only after an additional intervention that imposed contingencies on observing behavior. Thus, interventions that control observing behavior seem necessary but may not always be sufficient for the remediation of restricted stimulus control. 相似文献

Two experiments investigated recall following two study conditions, (1) repeated test: a study trial followed by multiple recall trials, and (2) repeated study: multiple study trials with no tests. At a retention interval of 5 minutes, repeated study produced a higher level of recall than repeated test. When the retention interval was extended, forgetting was much more rapid in the study condition, with the repeated test manipulation leading to higher recall at an interval of 7 days. We conclude that study and test trials have different effects upon memory, with study trials promoting memory acquisition, and test trials enhancing the retrieval process itself, which protects against subsequent forgetting. 相似文献

Research concerning the relations between stress and children’s memory has been primarily correlational and focused on memory volume and accuracy. In the current study, we experimentally manipulated 7- and 8-year-olds’ and 12- to 14-year-olds’ experienced stress during a to-be-remembered event to examine the effects of stress on the content of their memory. We further manipulated the degree of interviewer support at retrieval to determine whether it moderated the effects of stress at encoding on memory. Children’s age, gender, stress at encoding, and interviewer support all influenced the type of information included in their narrative reports. Most notably, across ages, children who experienced a more stressful event but were questioned in a supportive manner provided the largest ratio of terms representing internal states such as those about cognitions and emotions. Results suggest that how children process past events may be influenced by both the nature of the event itself and the context within which it is recalled. 相似文献

The hypothesis that dependency conflict is associated with higher levels of alcohol consumption when dependency needs are threatened or thwarted was tested with a sample of 672 middle-aged, married adults with college-age children. The subjects' current level of alcohol consumption was predicted based on the present level of threat to the marital relationship (assessed by reports from several family members) and on indices of dependency need and inhibition of dependent behavior estimated from sibship size, sibship density, and sibling position. A multiple regression analysis yielded a significant two-way interaction (p < .05) between marital threat and subject sex, and a significant three-way interaction of dependency heed, inhibition of dependent behavior, and marital threat. High marital threat was associated with higher levels of alcohol consumption in men and slightly lower levels of alcohol consumption in women. Additionally, when dependency need was high, alcohol consumption was generally low, except when both inhibition of dependent behavior and marital threat were high. However, when dependency need was low, the highest alcohol consumption score occurred when marital threat was low and inhibition was high. 相似文献

In a test of the discrepancy hypothesis of humor, Ss compared 11 comparison weights to a 90 gram standard. The 12th and 13th comparison weights were identical with, much lighter than, or heavier than the standard. More smile and laugh responses were made to the latter weights, and the number of these responses declined during the second presentation of those weights. The results supported the discrepancy hypothesis. 相似文献

In this paper, we provide a detailed critical review of current approaches to ecthesis in Aristotle’s Prior Analytics, with a view to motivate a new approach, which builds upon previous work by Marion & Rückert (2016) on the dictum de omni. This approach sets Aristotle’s work within the context of dialectic and uses Lorenzen’s dialogical logic, hereby reframed with use of Martin-Löf's constructive type theory as ‘immanent reasoning’. We then provide rules of syllogistic for the latter, and provide proofs of e-conversion, Darapti and Bocardo and e-subalternation, while showing how close to Aristotle’s text these proofs remain. 相似文献

Two experiments investigated the rate of forgetting for recently learned information in older and younger adults. Previous research has been inconclusive, with some studies reporting more rapid forgetting in older adults, whereas others have failed to find any age differences. In several different comparisons, older participants consistently forgot recently studied target words more rapidly than younger participants over a 1 hr retention interval. It appears that age-related difficulties in free recall become more pronounced as the interval between study and test increases, at least under some conditions. Results also confirm a powerful effect of prior testing on episodic memory: Both older and younger participants recalled more words after a delay of 1 hr if they had attempted recall shortly after the study session. 相似文献
