Under concurrent‐chains schedules of reinforcement, participants often prefer situations that allow selection among alternatives (free choice) to situations that do not (forced choice). The present experiment examined the effects of reinforcement probability on choice preferences. Preferences for free versus forced choice were measured under a condition in which participants' choices were always reinforced (reinforcement probability of 1.0) and a condition in which outcomes were uncertain (reinforcement probability of 0.5). Forty‐four college students participated and preferences were examined under a concurrent‐chains schedule of reinforcement. Participants preferred free choice under uncertain reinforcement, but a bias toward free choice was not observed when reinforcement was certain. These results align with previous findings of preference for free choice under conditions of uncertainty, but suggest that preference may be dependent upon probabilistic reinforcement contingencies in the terminal links of the concurrent‐chains arrangement. Thus, reinforcement probability is an important variable to consider when conducting similar studies on the value of choice. 相似文献

We assessed the effects of trainees observing and rating the accuracy of others implementing a paired-stimulus preference assessment from video on the trainees' subsequent implementation accuracy. These observational experiences increased implementation accuracy with both a confederate and an actual consumer. These results suggest conducting observations and accuracy ratings may prepare staff to implement behavioral procedures without need of a dedicated trainer. 相似文献

Empirical investigations of humans, pigeons, rats, and monkeys have indicated that these species will select free over forced choice, even when faced with identical outcomes. However, the same has yet to be quantitatively confirmed in nonhuman great apes. This experiment is the first systematic investigation of preference for free or forced choice in great apes using a paradigm in which extraneous variables are highly controlled. Three orangutans were given a choice of one of two virtual routes, one that provided a choice and one that did not via a touchscreen computer program. Choice of either route was rewarded with the same type and quantity of food. Initial results indicated a preference for free choice across all three participants. However, in two control conditions, orangutans' preferences varied, suggesting a weaker tendency to exercise choice than species previously tested. We suggest further investigation of preference for free and forced choice in orangutans and other great apes through alternative experimental paradigms that focus on increasing the fidelity of free and forced choice options. 相似文献

Pigeons and other animals sometimes deviate from optimal choice behavior when given informative signals for delayed outcomes. For example, when pigeons are given a choice between an alternative that always leads to food after a delay and an alternative that leads to food only half of the time after a delay, preference changes dramatically depending on whether the stimuli during the delays are correlated with (signal) the outcomes or not. With signaled outcomes, pigeons show a much greater preference for the suboptimal alternative than with unsignaled outcomes. Key variables and research findings related to this phenomenon are reviewed, including the effects of durations of the choice and delay periods, probability of reinforcement, and gaps in the signal. We interpret the available evidence as reflecting a preference induced by signals for good news in a context of uncertainty. Other explanations are briefly summarized and compared. 相似文献

In Study 1, we evaluated preference stability across 4 preference‐assessment methods for 6 individuals, 5 of whom had autism spectrum disorder and 1 of whom had traumatic brain injury. We also measured participants’ problem behavior as a corollary measure during all assessment methods. The highest mean correlation coefficients and Kendall rank coefficients of concordance across administrations were observed for the paired‐stimulus and multiple‐stimulus‐without‐replacement methods. Lower correspondence across administrations was observed for the free‐operant and response‐restriction methods. Although differentially higher levels of problem behavior did not occur with a single method, lower levels were consistently observed with the free‐operant method. During Study 2, we evaluated the implications of lower coefficients on reinforcer efficacy by comparing an initially identified and an immediately identified high‐preference stimulus in a reinforcer assessment. Initially identified and immediately identified high‐preference stimuli were equally effective reinforcers, suggesting that fluctuations in preference do not necessarily affect reinforcer efficacy in practice. 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

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

In the United States, Black Americans’ counseling experiences are associated with concerns that are unique to their racialized status. Understanding the range of cultural factors that influence Black Americans’ preferences in the context of counseling remains an important topic in marketing and providing high-quality counseling services to this population. Thus, the purpose of this study was to examine the role of racial centrality, affirming socialization around race, and minority status stress on counselor racial preference among Black college students (N = 139) in the United States. Results from a hierarchical multiple regression revealed that racial centrality and minority stress independently predicted preference for a racially similar counselor in this sample of respondents. A significant interaction between minority stress and affirming racial socialization revealed that the effect of minority status stress on counselor racial preference was attenuated at high levels of affirming racial socialization. Findings are discussed in the context of racial identity and racial socialization theories, with emphasis on implications for counseling practice and clinical training. 相似文献
