刺激呈现次数和位置对纯粹接触效应的影响研究

纯粹接触效应是指个体接触一个刺激的次数越频繁,个体对该刺激就越喜欢的现象。本文通过两个实验考察刺激的呈现次数与位置对纯粹接触效应的影响。实验1讨论了纯粹接触效应与刺激呈现次数之间的关系,发现刺激的偏好程度和再认成绩在不同的刺激呈现次数水平上都具有显著性差异。实验2讨论了纯粹接触效应与刺激呈现位置之间的关系,结果发现不同呈现位置上刺激的偏好程度不具有显著性差异,而再认成绩之间具有显著性差异。     

品牌忠诚：概念、测量和相关因素

早期研究者对品牌忠诚的定义多是操作性的,主要为行为论和态度论观点。将品牌忠诚看作复杂多维度概念,则成为当前研究者广泛接受的观点。品牌忠诚度是对消费者品牌忠诚的测量,依研究目的不同而有多种形式。消费者认知、态度和行为方面的一些变量,和品牌忠诚相互作用。     

品牌延伸中母品牌的作用机制

品牌延伸研究近年来受到了国外营销学界的普遍关注,母品牌在延伸行为中的作用机制是其中的一个热点问题。文章在查阅有关文献的基础上,对该领域影响比较大的两个延伸评价模型,情感迁移模型和联想需求模型,进行了较为深入的介绍、评述和比较。两个模型都从消费者认知的角度来理解延伸评价的形成,其中涉及到刺激泛化、类化和精细计算加工等认知过程。     

品牌形象的消费行为学研究

品牌形象是消费者头脑中与某一品牌相关联的属性集合和相关联想,是消费者对品牌的主观反映。作者在介绍有关国内外从消费行为学的角度进行品牌形象研究的基础上,就品牌形象的消费行为学研究提出了一些新的思路。     

Uncovering the links between brand choice and personal values among young British and Spanish girls

This paper presents empirical research which demonstrates how snacks brands can satisfy certain personal values for female 11–12 year‐old British and Spanish consumers. The qualitative research design uses a means‐end approach, based on a laddering technique, to uncover the links between brand choice and personal values. After reviewing the means‐end model and other relevant theory, the research methodology and design are presented in detail. The findings reveal significant scope for positioning snacks brands using the values of well being and fun and enjoyment (UK and Spain), while the value of friendship and belonging emerges as an extra dimension for the British respondents.

Functional analysis and treatment of self-injury associated with transitions.

We applied functional analysis methodology to the assessment and treatment of 2 individuals' self‐injurious behavior (SIB), which was reported to be occasioned by transitions from one activity or location to another. A structural (task) analysis of activity transitions identified at least three separate components that might influence behavior either alone or in combination: (a) termination of a prechange activity, (b) initiation of a postchange activity, and (c) movement from one location to another. Results of preference and avoidance assessments were used to identify activities to which participants were exposed in varying arrangements during transitions in a functional analysis. Results of 1 participant's functional analysis indicated that his SIB was maintained by avoidance of having to change locations, regardless of the activity terminated prior to the change or the activity initiated following it. The 2nd participant's analysis revealed the same function but also an additional one: avoidance of certain task initiations. This information was used to identify transition contexts during intervention and to design treatment procedures appropriate for a given context and behavioral function. A procedure involving advance notice of an upcoming transition had no effect on SIB, and differential reinforcement of alternative behavior (DRA) had limited effects in the absence of extinction. Sustained decreases in SIB were observed when DRA was combined with extinction and response blocking. Further extensions of functional analysis methodology to the assessment of problem behavior in situations characterized by multiple or protracted stimulus changes are discussed.     

Evaluating the predictive validity of a single stimulus engagement preference assessment.

Most preference assessments require individuals to choose among two or more stimuli. More recently, the duration of engagement with items has been used as an index of preference. In the current study, the predictive validity of a single stimulus engagement (SSE) preference assessment was evaluated with 4 individuals. Stimuli were presented singly for a brief period while engagement with that stimulus was recorded. Although SSE preference rankings closely matched paired stimulus preference assessment rankings for only 2 of the 4 participants, relative preference rankings based on duration of engagement predicted relative reinforcer effectiveness for all participants in a subsequent concurrent‐schedule reinforcer assessment. The SSE procedure took less time to administer than the paired stimulus procedure but produced less stable preference rankings across administrations. The SSE procedure may be appropriate for individuals who have difficulty selecting one stimulus from among two or more stimuli, and it may be well suited for evaluating activities that are difficult to present in a paired stimulus format.     

Preference for free or forced choice in Sumatran orangutans (Pongo abelii)

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.     

Testing for DIF in a model with single peaked item characteristic curves: The parella model

The PARELLA model is a probabilistic parallelogram model that can be used for the measurement of latent attitudes or latent preferences. The data analyzed are the dichotomous responses of persons to items, with a one (zero) indicating agreement (disagreement) with the content of the item. The model provides a unidimensional representation of persons and items. The response probabilities are a function of the distance between person and item: the smaller the distance, the larger the probability that a person will agree with the content of the item. This paper discusses how the approach to differential item functioning presented by Thissen, Steinberg, and Wainer can be implemented for the PARELLA model.

Improving assignment preference through interspersing additional problems: Brief versus easy problems

College students were exposed to a control mathematics assignment containing 16 three-digit by two-digit multiplication (3×2) problems and two experimental assignments that contained 16 equivalent 3×2 problems and six additional interspersed problems. On one experimental assignment, 4-digit plus 4-digit problems (4+4) were interspersed. On the other experimental assignment, 2-digit divided by 1-digit with whole number answers problems (2/1) were interspersed. When given a choice, significantly more students choose the 2/1 assignment over the control and 1+4 assignment. Students also ranked the 2/1 sheet as requiring less time to complete than the control or 4+4 assignment but no differences were found on assignment difficulty rankings between the 4+4 and 2/1 assignments. No differences were found on accuracy levels or rates of responding on the target 3×2 problems across assignments. Results showed that interspersing additional problems that take relatively less time to complete may be more important for altering student preference for assignments than interspersing easier problems. Discussion focuses on schedules of reinforcement and resource efficient procedures for increasing student preference for assignment without compromising curricula integrity.
