The purpose of this systematic review was to identify investigations comparing the efficacy of alternative modality (e.g., pictorial, verbal, video) stimulus preference assessments for individuals with developmental disabilities. We identified articles by searching peer‐reviewed journals using the PsycINFO and ERIC databases, conducting table of contents searches of common behavioral outlets, and conducting ancestral searches of recent reviews and practitioner summaries of preference assessment methodology. A total of 32 articles met our inclusion criteria. These studies were then coded across a variety of features to gain a better understanding of the efficacy of alternative format preference assessments for individuals with developmental disabilities. In addition, we reviewed this literature for the use of prerequisite‐skill assessments and contingent‐reinforcer access to further investigate the relation between these variables and the accuracy of pictorial, verbal, and video preference assessments. A variety of methodological concerns are discussed as well as suggestions for future research. 相似文献

A pictorial preference assessment was conducted for 2 individuals with autism who had programmed breaks in their behavior plans. Assessed break environments were individualized, based on indirect assessments and direct observations. The most highly (HP) and least preferred (LP) environments and a control with no associated break were included in a subsequent reinforcer assessment using a concurrent‐chains arrangement within a reversal design. Participants selected a multitask sequence (initial link) associated with one of the break environments. Phase A evaluated the reinforcing properties of all three breaks; the HP was removed in Phase B. Both participants allocated more responding to HP than LP, and to LP than control, suggesting that breaks functioned as reinforcers. The results indicated that preference assessment technology can be used to identify highly preferred breaks that function as reinforcers. Social validity measures indicated that the individuals' clinicians found the results useful for future clinical programming. 相似文献

We used a reversal design with an embedded multielement design to compare the effects of an independent group contingency and a randomized dependent group contingency on compliance with assigned literacy worksheets in a first‐grade general education classroom. Nine participants were selected based on low levels of compliance in baseline or by teacher identification. Results indicated that both group contingencies increased compliance relative to baseline for the majority of participants. The independent condition produced higher levels of compliance for four students and the randomized dependent condition produced higher levels of compliance for one student. For four students, the two group contingencies were equally effective. A preference assessment indicated that the majority of target students preferred the randomized dependent condition and the majority of nontarget students preferred the independent condition. A number of potential explanations for our preference findings, including the possible role of obtained reinforcement, are discussed. 相似文献

During shaping, if the organism is engaged in behaviors other than the current approximation, the amount of time between reinforcers increases. In these situations, the shaper may resort to what is referred to as a “desperation‐driven click.” That is, after a period of no reinforcement, the shaper delivers one reinforcer for a nontarget approximation. Reports from professional animal trainers suggest that the animal may continue performing this new behavior, even if it is reinforced only once. This study attempted to model this phenomenon with college students. Results from the study demonstrated that a desperation‐driven click situation can be reliably produced in a controlled setting. When participants received one reinforcer for interacting with a new object following a period of no reinforcement, they interacted with the new object for a longer or equal amount of time as compared to an object that had a longer history of reinforcement. The results of this study have implications for the understanding of how reinforcement controls behavior. 相似文献

Simple and conditional discrimination training may produce various types of controlling relations. Responses may be controlled primarily by the positive stimulus (select–control relation) or by the negative stimulus (reject–control relation; the subject excludes the negative stimulus and chooses the positive). Bees learn to respond in simple and conditional discriminations. However, no study has searched for reject–control responding in Melipona bees. We trained Melipona quadrifasciata on a simple discrimination task (S+ vs. S‐; e.g., blue vs. yellow) and then probed for stimulus control with two types of probe trials, S+ versus a new stimulus (Select–control probes) and S‐ versus a new stimulus (Reject–control probes). For Group Different, a new‐stimulus color (e.g., white) was used in one type of probe and another color (e.g., black) was used in the other type. For Group Same, a single new‐stimulus color was used in both types of probes. On Select probes, the bees always preferred S+ to the new stimulus. On Reject probes, results were mixed. Depending on the colors used in training and probing, bees responded to both stimuli, and even preferred the S‐. The data suggest no control by the negative function of the S‐ and support the select‐stimulus control hypothesis of responding. 相似文献

In Japan, implementation of suicide prevention policies is mainly supported by public funds. However, it is unclear what kinds of suicide prevention strategies people prefer. We conducted a survey to clarify people’s preferences regarding suicide prevention strategies adopted in Japan. This was a cross-sectional self-administered questionnaire survey. Participants were recruited through a lecture held by the first author at their university. We distributed questionnaires to 324 people present at the lecture; 249 completed questionnaires were included in the final analysis. We estimated suicide prevention strategy preferences using full profile conjoint analysis. For all six prevention strategies, the inclusion of each strategy in the policy profile was statistically significantly related to the positive evaluation of the overall policy profile. Marginal Willingness to Pay (MWTP) for restriction of access to means showed the highest value of the six suicide prevention strategies. MWTP was the lowest for public awareness activities. Preferred suicide prevention strategies in Japan are restriction of access to means and enhancement of psychiatric services. The results of this study indicate the strategies that are preferred have a high level of evidence of suicide prevention and do not directly intervene in a person’s free will to die by suicide. 相似文献

Bicycles are an environmentally-friendly, energy-saving mode of transportation. Public bike-and-ride is a term used to describe the use of public bicycles combined with transit as a means of transportation. A new stated preference (SP) design scheme based on the factors respondents felt were most important was proposed to augment the traditional SP design under complex multi-factor and multi-level situations. iPads were used to automatically administer the survey under each design scheme and collect the choice behavior data for public bike-and-ride. The concept of perceived psychological distance was further proposed and used to estimate Logit models. Comparative analysis of these models shows for the traditional SP design scheme, some factors, including perceived psychological distance, have reduced statistically significant effects on public bike-and-ride choice relative to the new SP design scheme. This indicates that in scenarios with complex decisions, the decision-makers would reduce their consideration of some factors and simplify their decision process making the new SP survey design scheme more suitable to analyze their choice behavior in those cases. Model analysis showed that perceived psychological distance for each traveler is the most critical factor during the decision process for travel behavior analysis. Finally, sensitivity analysis was conducted to determine which factors in the new survey design were important to increase the share of public bike-and-ride users. Practical findings for promoting public bike-and-ride use are presented in addition to theoretical references for improving the traditional survey methods. 相似文献

The author's purpose was to examine children's recognition of emotional facial expressions, by comparing two types of stimulus: photographs and drawings. The author aimed to investigate whether drawings could be considered as a more evocative material than photographs, as a function of age and emotion. Five- and 7-year-old children were presented with photographs and drawings displaying facial expressions of 4 basic emotions (i.e., happiness, sadness, anger, and fear) and were asked to perform a matching task by pointing to the face corresponding to the target emotion labeled by the experimenter. The photographs we used were selected from the Radboud Faces Database and the drawings were designed on the basis of both the facial components involved in the expression of these emotions and the graphic cues children tend to use when asked to depict these emotions in their own drawings. Our results show that drawings are better recognized than photographs, for sadness, anger, and fear (with no difference for happiness, due to a ceiling effect). And that the difference between the 2 types of stimuli tends to be more important for 5-year-olds compared to 7-year-olds. These results are discussed in view of their implications, both for future research and for practical application. 相似文献

We propose quantitative experimental approaches to the question of whether positive and negative reinforcement are functionally different, and discuss scientific and ethical concerns that would arise if these approaches were pursued. 相似文献

Aim of this study was to investigate the preferential looking behaviour, subsequent to a familiarization task (8-min) with a previously responsive or motionless face, before and after a sleep cycle. Moreover, the role of the active sleep in memory consolidation of the responsive or motionless faces was explored. Hypotheses were that the newborns undergoing a motionless familiarization will exhibit a novelty effect (preference for the novel face) whereas the newborns undergoing a responsive familiarization will show a familiarity effect (preference for the known face) before and after the sleep cycle; moreover, the amount of active sleep will be associated with the looking time at the known face after a sleep cycle.Forty-five healthy full-term newborns were randomly assigned to two groups (group 1: motionless-familiarization and group 2: responsive-familiarization); in both groups newborns were video-recorded during four post-familiarization face-preference tasks, two of them performed before and two after a sleep cycle.During the pre-sleep-trials, there was not a significant preference for one face in both groups. During the post-sleep trials, the newborns showed a clear preference for the novel face. This effect was more evident in group 1. Only in group 2 there was a significant positive correlation between the active sleep duration and the looking duration at the known-face during the post-sleep trials (r = 0.41; p = 0.040). Multiple regression confirmed that only in the group 2 the total duration of the active sleep was associated with the looking duration at the known-face during the post-sleep trials (Adjusted R2 = 0.13; β = 0.41; t = 2.2; p = 0.040).Findings showed that in newborns the face representation can be recalled after a sleep cycle. Moreover, the amount of the active sleep predicted the post-sleep looking toward the known-face only in the newborns who interactively familiarized with the face. 相似文献
