IS IT ALL IN THE NUMBERS? A Case Study of Tokenism

The purpose of the present study is to explore whether the negative consequences of tokenism are the result of imbalanced proportions alone, or whether society-wide sex role stereotypes which affect male and female tokens differently are also a factor. Men working at concession stands at an amusement attraction were assigned by the experimenters to one of two work groups in which the numbers of women and men were either skewed or balanced. Unlike a token woman at the attraction, these token male workers did not experience the negative consequences of tokenism (visibility, contrast, and assimilation). In fact, token men identified with supervisors and advanced more quickly than their non-token counterparts of both sexes. The results are interpreted as indicating that underrepresentation alone cannot explain the negative effects of tokenism for women.     

Reversing roles: a cognitive strategy for undoing memory deficits associated with token status

Tested whether having tokens (Ts) adopt the role of judge reduces cognitive deficits; examined several hypotheses to explain these deficits. In 3 experiments, Ss were asked to remember as many as possible of opinions exchanged in a group interaction with 3 actors. Experiment 1 demonstrated that judging majority members helped gender Ts improve their memory and ruled out self-denigration as a mediator of token deficits. Experiment 2 indicated that judging others was effective regardless of whether the others were said to know about it or not, ruling out insulation from evaluative scrutiny as a viable mediator for the judge role. Experiment 3 suggested the judge role restores completely the Ts, cognitive capacities and ruled out heightened responsibility as an explanation for the improved memory of judges. This work suggests that Ts may perform better if they can restructure cognitively their social environments.     

The influence of sexually explicit Internet material and peers on stereotypical beliefs about women's sexual roles: similarities and differences between adolescents and adults

Previous research on the influence of sexually explicit Internet material (SEIM) on adolescents' stereotypical beliefs about women's sexual roles has three shortcomings. First, the role of peers has been neglected; second, stereotypical beliefs have rarely been studied as causing the use of SEIM and the selection of specific peers; and third, it is unclear whether adolescents are more vulnerable to the effects of SEIM than adults. We used data from two nationally representative two-wave panel surveys among 1,445 Dutch adolescents and 833 Dutch adults, focusing on the stereotypical belief that women engage in token resistance to sex (i.e., the notion that women say "no" when they actually intend to have sex). Structural equation modeling showed that peers who supported traditional gender roles elicited, both among adolescents and adults, stronger beliefs that women use token resistance to sex. Further, the belief that women engage in token resistance predicted adolescents' and adults' selection of gender-role traditional peers, but it did not predict adolescents' and adults' use of SEIM. Finally, adults, but not adolescents, were susceptible to the impact of SEIM on beliefs that women engage in token resistance to sex.     

Non‐generalized and generalized conditioned reinforcers: establishment and validation

Conditioned reinforcers, or tokens, are frequently used in clinical settings; however, little applied research has focused on establishing and validating their effectiveness. Following pairing of a novel token with an edible reinforcer in the present study, preference and reinforcer assessments verified that the tokens functioned as conditioned reinforcers. Results indicated that the tokens were established as conditioned reinforcers that matched the reinforcer value of the primary reinforcers with which they had been paired. The effects of motivating operations (MOs) on the effectiveness of these conditioned reinforcers were then evaluated. Conditioned reinforcer effectiveness decreased during satiation conditions. Subsequently it was found that increasing the number of backup reinforcers with which the token was paired resulted in the effectiveness maintaining during satiation conditions.

Token transfer between mother and offspring chimpanzees (Pan troglodytes): mother–offspring interaction in a competitive situation

Chimpanzees can flexibly use tokens in cognitive tasks, but it is still unknown if they can share and/or compete over tokens as they do for food. This study aimed to evaluate the interactions spontaneously occurring between mother and offspring chimpanzees when tokens exchangeable for food were provided. Forty tokens were scattered on the floor in an experimental playroom. Three mother and offspring chimpanzee pairs were tested. Each token was exchangeable for a piece of food in a vending machine installed on the wall of the playroom. In the beginning of the study, both mother and offspring took tokens and exchanged them for pieces of food independently. Later, two offspring started to take more tokens than their mothers. At that time, the offspring whimpered or cried more often than during earlier sessions. This behavior compelled the mothers to abstain from taking tokens. The mothers sometimes shared their tokens with their offspring, or were tolerant of their offspring taking their tokens from their hand. For one pair, the offspring sometimes shared tokens with her mother when her mother begged for the tokens. These results suggest that chimpanzees’ cognitive abilities enable them not only to use tokens, but also to compete for tokens, as they do for food. The results also suggest that token sharing between mother and offspring may be bidirectional and that transfer of tokens mainly occurs as a result of begging, although on some occasion offspring were able to obtain a token directly from his/her mother through tolerated scrounging.     

Using progressive ratio schedules to evaluate tokens as generalized conditioned reinforcers

The properties of operant reinforcers are dynamic and dependent on a number of variables, such as schedule and effort. There has been sparse research on the generalized conditioned properties of token reinforcement. We evaluated leisure items, edible items, and tokens using a progressive ratio schedule with three children with diagnoses of ASD and developmental delays. The highest break points occurred during the token reinforcement condition for two out of three participants, but response rates tended to be higher with edibles. We then evaluated the effects of presession access to edibles on the break points of edible items and tokens with two participants. Break points decreased only in the edible reinforcement condition, and the participants chose to work for leisure items rather than edibles when presession access to edibles was in place. These findings suggest that the tokens functioned as generalized conditioned reinforcers.     

Predicting Men's Rape Perceptions Based on the Belief That "No" Really Means "Yes"

This study tested men's perceptions of rape based on the belief that women use token resistance to sex—that they say "no" to sex when they really mean "yes." Participants were 131 male undergraduates who completed the Token Resistance to Sex scale and responded to evaluative statements regarding 1 of 3 scenarios: rape, consent, or ambiguous. Results supported the hypothesis that men with a weaker belief in token resistance would have stronger perceptions of rape when a woman said "no" to sex than when a woman said "yes," and that men with a stronger belief in token resistance would have weak perceptions of rape in both situations. These findings implicate miscommunication as a potential contributing factor in date rape.     

Substitution effects in a generalized token economy with pigeons

Pigeons made repeated choices between earning and exchanging reinforcer‐specific tokens (green tokens exchangeable for food, red tokens exchangeable for water) and reinforcer‐general tokens (white tokens exchangeable for food or water) in a closed token economy. Food and green food tokens could be earned on one panel; water and red water tokens could be earned on a second panel; white generalized tokens could be earned on either panel. Responses on one key produced tokens according to a fixed‐ratio schedule, whereas responses on a second key produced exchange periods, during which all previously earned tokens could be exchanged for the appropriate commodity. Most conditions were conducted in a closed economy, and pigeons distributed their token allocation in ways that permitted food and water consumption. When the price of all tokens was equal and low, most pigeons preferred the generalized tokens. When token‐production prices were manipulated, pigeons reduced production of the tokens that increased in price while increasing production of the generalized tokens that remained at a fixed price. The latter is consistent with a substitution effect: Generalized tokens increased and were exchanged for the more expensive reinforcer. When food and water were made freely available outside the session, token production and exchange was sharply reduced but was not eliminated, even in conditions when it no longer produced tokens. The results join with other recent data in showing sustained generalized functions of token reinforcers, and demonstrate the utility of token‐economic methods for assessing demand for and substitution among multiple commodities in a laboratory context.     

Sex,hypermasculinity, and hyperfemininity in perception of social cues in neutral interactions

Sexual coercion is a prevalent problem on U.S. college campuses. One potential avenue by which it may occur is the misinterpretation of social cues, and such misperception may be mediated by extreme sex role adherence, i.e., hypermasculinity and hyperfemininity. 62 undergraduate students viewed a film of a neutral interaction between a college-aged man and woman. Subsequently, participants indicated which behaviors they remembered the opposite-sex actor performing, offered a prediction as to the outcome of the scenario and what they would do had they been in a similar situation, and then completed either the Hypermasculinity Inventory or the Hyperfemininity Scale. Scores on the former correlated negatively with recall accuracy, and men indicated that they were more likely to date and have sex with the actress than women reported being likely to date or have sex with the actor. Women reported a high perceived likelihood of dating the actor coupled with the expectation that he would have sex with the actress. Likewise, women expected to be sexually coerced by the actor had they been in a similar situation. Social implications of these findings and possible research are discussed.     

Are monkeys able to plan for future exchange?

Whether or not non-human animals can plan for the future is a hotly debated issue. We investigate this question further and use a planning-to-exchange task to study future planning in the cooperative domain in two species of monkeys: the brown capuchin (Cebus apella) and the Tonkean macaque (Macaca tonkeana). The rationale required subjects to plan for a future opportunity to exchange tokens for food by collecting tokens several minutes in advance. Subjects who successfully planned for the exchange task were expected to select suitable tokens during a collection period (5/10?min), save them for a fixed period of time (20/30?min), then take them into an adjacent compartment and exchange them for food with an experimenter. Monkeys mostly failed to transport tokens when entering the testing compartment; hence, they do not seem able to plan for a future exchange with a human partner. Three subjects did however manage to solve the task several times, albeit at very low rates. They brought the correct version of three possible token types, but rarely transported more than one suitable token at a time. Given that the frequency of token manipulation predicted transport, success might have occurred by chance. This was not the case, however, since in most cases subjects were not already holding the token in their hands before they entered the testing compartment. Instead, these results may reflect subjects' strengths and weaknesses in their time-related comprehension of the task.     

Do women sometimes say no when they mean yes? The prevalence and correlates of women's token resistance to sex

We investigated whether women ever engage in token resistance to sex--saying no but meaning yes--and, if they do, what their reasons are for doing so. A questionnaire administered to 610 undergraduate women asked whether they had ever engaged in token resistance and, if so, asked them to rate the importance of 26 possible reasons. We found that 39.3% of the women had engaged in token resistance at least once. Their reasons fell into three categories: practical, inhibition-related, and manipulative reasons. Women's gender role attitudes, erotophobia-erotophilia, and other attitudes and beliefs varied as a function of their experience with token resistance and their sexual experience. We argue that, given society's sexual double standard, token resistance may be a rational behavior. It could, however, have negative consequences, including discouraging honest communication, perpetuating restrictive gender stereotypes, and--if men learn to disregard women's refusals--increasing the incidence of rape.     

Preferences for token exchange‐production schedules: Effects of task difficulty and token‐production schedules

Previous research suggests that accumulated exchange‐production schedules promote increased work completion and are more preferred than distributed exchange‐production schedules. The purpose of this study was to evaluate whether the response effort or token‐production schedules associated with token delivery influenced preferences for exchange‐production schedules. Tokens exchanged under accumulated schedules were more preferred, relative to distributed schedules, when tokens were earned for completing easy tasks. When participants earned tokens for completing difficult tasks, two of three participants preferred accumulated exchange‐production schedules (Experiment 1). Under dense token‐production schedules, accumulated exchange‐production schedules were preferred, but participant's preferences switched to distributed schedules under increasing token‐production (i.e., leaner) schedules (Experiment 2).     

Awareness of Recognition Memory for Polish and English Folk Songs in Polish and English Folk

Polish and English people listened either once or three times to excerpts from Polish and English folk songs before being given a recognition test in which, when recognising an excerpt, they had to report whether they remembered hearing it, knew they had heard it, or guessed they had heard it. Both Polish and English people remembered more of the excerpts from their own folk songs, and they remembered more of the excerpts they heard three times rather than once, regardless of the national background of the songs. They also knew they had heard more of the excerpts they heard three times, but only if they were from the other folk's songs. Repetition did not affect knowing songs from one's own national background. These findings confirm and extend previous findings suggesting that remembering and knowing are functionally independent states of awareness.     

The effects of token reinforcement,feedback and response cost on standardized test performance

The primary purpose of the present study was to compare the differential effects of token reinforcement, feedback, and response cost on the test performance of delinquent boys. Eighty students were randomly assigned to three experimental groups and one control group of 20 subjects each. Each experimental group received a standard and a modified administration of the verbal section of the WISC. For the token reinforcement group, the modified WISC administration permitted students to earn tokens contingent on correct responses; the response cost group forfeited tokens contingent on incorrect responses; and the feedback group simply received information regarding the accuracy of each response. The control group received two standard WISC administrations. The primary measure was the difference in verbal I.Q. scores between the standard and modified WISC administrations. Results indicated that the token reinforcement and response cost groups achieved significantly higher scores than the feedback and control groups. No significant differences were found between the token reinforcement and response cost groups nor between the feedback and control groups. The implications of these findings for clarifying the relationship between motivational condition and test performance are discussed.     

Effects of a Perseverative Interest-Based Token Economy on Challenging and On-Task Behavior in a Child with Autism

We compared the effects of a token economy intervention that either did or did not include the perseverative interests of a 7-year-old boy with autism. An alternating treatment design revealed that the perseverative interest-based tokens were more effective at decreasing challenging behavior and increasing on-task behavior than tokens absent the perseverative interest during an early literacy activity. The beneficial effects were then replicated in the child’s classroom. The results suggest that perseverative interest-based tokens might enhance the effectiveness of interventions based on token economies.     

Token mediated tool exchange between tufted capuchin monkeys (<Emphasis Type="Italic">Cebus apella</Emphasis>)

Three experiments were conducted to test whether a pair of tufted capuchin monkeys (Cebus apella) could generalize their ability to exchange tokens and tool objects with a human experimenter to similar exchanges with a conspecific partner. Monkeys were tested in side-by-side enclosures, one enclosure containing a tool-use apparatus and one or more token(s), and the other enclosure containing one or more tool object(s). The monkeys willingly transferred tokens and tools to a conspecific with little practice. Following a small amount of training, we also found that the monkeys would select situation-appropriate tokens to exchange for specific tools, but did not select appropriate tool objects in response to another monkey’s token transfers. Implications regarding role reversal are discussed.     

Token reinforcement, choice, and self-control in pigeons.

Pigeons were exposed to self-control procedures that involved illumination of light-emitting diodes (LEDs) as a form of token reinforcement. In a discrete-trials arrangement, subjects chose between one and three LEDs; each LED was exchangeable for 2-s access to food during distinct posttrial exchange periods. In Experiment 1, subjects generally preferred the immediate presentation of a single LED over the delayed presentation of three LEDs, but differences in the delay to the exchange period between the two options prevented a clear assessment of the relative influence of LED delay and exchange-period delay as determinants of choice. In Experiment 2, in which delays to the exchange period from either alternative were equal in most conditions, all subjects preferred the delayed three LEDs more often than in Experiment-1. In Experiment 3, subjects preferred the option that resulted in a greater amount of food more often if the choices also produced LEDs than if they did not. In Experiment 4, preference for the delayed three LEDs was obtained when delays to the exchange period were equal, but reversed in favor of an immediate single LED when the latter choice also resulted in quicker access to exchange periods. The overall pattern of results suggests that (a) delay to the exchange period is a more critical determinant of choice than is delay to token presentation; (b) tokens may function as conditioned reinforcers, although their discriminative properties may be responsible for the self-control that occurs under token reinforcer arrangements; and (c) previously reported differences in the self-control choices of humans and pigeons may have resulted at least in part from the procedural conventions of using token reinforcers with human subjects and food reinforcers with pigeon subjects.     

The effects of token procedures on a teacher's social contacts with her students

The effects of a token system on a teacher's rate of social contacts with her students were investigated in a public school kindergarten. A group of six children were observed daily during a 20-min handwriting lesson. The children were divided into two groups (A and B) of three children each. Five conditions were imposed sequentially: (1) baseline without tokens, (2) contingent tokens for Group A, noncontingent tokens for Group B, (3) contingent tokens for Group B, noncontingent tokens for Group A, (4) reinstatement of condition 2, and (5) contingent tokens for both groups. It was consistently observed that the teacher's rate of social contact was higher with the children receiving the contingent tokens than with those who received noncontingent tokens.     

Socially learned preferences for differentially rewarded tokens in the brown capuchin monkey (Cebus apella)

Social learning is assumed to underlie traditions, yet evidence indicating social learning in capuchin monkeys (Cebus apella), which exhibit traditions, is sparse. The authors tested capuchins for their ability to learn the value of novel tokens using a previously familiar token-exchange economy. Capuchins change their preferences in favor of a token worth a high-value food reward after watching a conspecific model exchange 2 differentially rewarded tokens, yet they fail to develop a similar preference after watching tokens paired with foods in the absence of a conspecific model. They also fail to learn that the value of familiar tokens has changed. Information about token value is available in all situations, but capuchins seem to pay more attention in a social situation involving novel tokens.     

Numerical judgments by chimpanzees (Pan troglodytes) in a token economy

We presented four chimpanzees with a series of tasks that involved comparing two token sets or comparing a token set to a quantity of food. Selected tokens could be exchanged for food items on a one-to-one basis. Chimpanzees successfully selected the larger numerical set for comparisons of 1 to 5 items when both sets were visible and when sets were presented through one-by-one addition of tokens into two opaque containers. Two of four chimpanzees used the number of tokens and food items to guide responding in all conditions, rather than relying on token color, size, total amount, or duration of set presentation. These results demonstrate that judgments of simultaneous and sequential sets of stimuli are made by some chimpanzees on the basis of the numerousness of sets rather than other non-numerical dimensions. The tokens were treated as equivalent to food items on the basis of their numerousness, and the chimpanzees maximized reward by choosing the larger number of items in all situations.
