An automated regional taste-testing system

A fully programmable and portable automated regional taste-testing system is described. This system utilizes a glass stimulator held to the surface of the tongue by a mild vacuum. Temporally and spatially discrete trains of stimuli, delivered from a bank of glass reservoirs through microprocessor-controlled Teflon solenoid valves and both glass and Tygon tubing, can be delivered to the lingual surface at millisecond durations. Rinses between stimuli are similarly programmed. The stimulus delivery is monitored at the surface of the tongue, using a capacitance sensor to alert the subject of stimulus delivery. An example of the application of this system is shown, in which we demonstrate that the detection threshold for NaCl is inversely related to stimulus duration by a power function.     

Poor emotional responsiveness in clinical hypertension: Reduced accuracy in the labelling and matching of emotional faces amongst individuals with hypertension and prehypertension

Psychological factors are known to play an important part in the origin of many medical conditions including hypertension. Recent studies have reported elevated blood pressure (even in the normal range of variation) to be associated with a reduced responsiveness to emotions or ‘emotional dampening’. Our aim was to assess emotional dampening in individuals with more extreme blood pressure levels including prehypertensives (N = 58) and hypertensives (N = 60) by comparing their emotion recognition ability with normotensives (N = 57). Participants completed novel facial emotion matching and facial emotion labelling tasks following blood pressure measurement and their accuracy of emotion recognition and average response times were compared. The normotensives demonstrated a significantly higher accuracy of emotion recognition than the prehypertensives and the hypertensives in labelling of facial emotions. This difference generalised to the task where two facial halves (upper & lower) had to be matched on the basis of emotions. In neither the labelling nor matching emotion conditions did the groups differ in their speed of emotion processing. Findings of the present study extend reports of ‘emotional dampening’ to hypertensives as well as to those at-risk for developing hypertension (i.e. prehypertensives) and have important implications for understanding the psychological component of such medical conditions as hypertension.     

The effect of stress on craving for methadone depends on the timing of last methadone dose

Background

This study examined the extent to which the timing of last methadone dose moderates the influence of a laboratory stressor on craving for methadone in a sample of methadone maintenance patients.

Methods

Methadone maintenance patients (N = 41) completed a computerized stress manipulation with two levels (low and high stress) on two separate days: (1) immediately following the administration of their standard daily methadone dose and (2) immediately prior to receiving their standard daily dose. The impact of stress, timing of methadone dose and their interaction were examined on self-report measures of stress and craving for methadone.

Results

Craving ratings varied according to the timing of last methadone dose. Immediately following methadone dose (i.e., day 1), there was no effect for stress on craving (0.12; p = 0.30). However, prior to receiving methadone dose (i.e., day 2), the high stress effect on craving was significant (1.51; p < 0.001).

Discussion

The present findings indicate that patients currently receiving methadone maintenance treatment may be particularly vulnerable to stress-related relapse immediately prior to daily methadone dosing.     

Prepurchase Attribute Verifiability,Source Credibility,and Persuasion

Recent research has found that search and experience attribute claims are processed differently by consumers, with search attribute claims typically being more believable than experience attribute claims. It is, however, routinely the case that marketers desire to promote a product by making a claim featuring an experience attribute. The marketing literature has largely neglected the issue of how to enhance persuasion of experience attribute claims. The purpose of this research was to fill this void. We reason that source credibility impacts the receipt of experience claims and search claims differently. We then report results of 2 experiments featuring 2 different types of sources in the context of 2 different categories that suggest a source high in credibility can be employed to make experience claims more persuasive. The contributions our study makes to the persuasion literature and avenues for future research are discussed.     

Artificial intelligence consumer behavior: A hybrid review and research agenda

The advancement of artificial intelligence (AI) technology and its applications has drastically transformed consumer behavior (CB). As consumers interact with these applications on multiple platforms and touchpoints, it becomes crucial to understand how these interactions affect consumer behavior and its components, including personality, attitude, engagement, decision-making, and trust. The research on the relationship between artificial intelligence and consumer behavior (hereafter referred to as AI CB) revolves around these topics and has grown exponentially in recent years. A rigorous review is required to provide directions for future studies by comprehending the extensive literature, understanding research gaps, and identifying the future directions for scholarly work. This article aims to address this research gap by analyzing 107 AI CB articles using the bibliometric and framework-based methodology to provide insights into publication trends, dominant theories, methods, antecedents, decisions, and outcomes in the AI CB literature. Most importantly, the review identifies clusters of research fronts and provides a thematic framework for current research. These clusters or themes relate to AI interaction with consumer behavior dimensions, including consumer acceptance and trust, consumer interaction and engagement, attitude and personality, decision-making, and adoption. This thematic framework and TCM-ADO analysis offer future research directions to advance theory development and have implications for industry and society.     

Exploring the role of augmented reality as a new brand advocate

Augmented reality (AR) has proven to be a potential source of disruption in the marketing discipline. Abundant research has attested to AR's potential by exploring the impact of AR attributes on behavioral intentions and users' attitudes. However, AR's potential to spark customer interactions, co-create value, and foster brand advocacy remains poorly understood. This study explores whether and how AR can turn users into brand advocates. Applying structural equation modeling to a sample of 502 AR users, the study finds that AR empowers users during their shopping experience, creating strong brand attachment and engagement and ultimately leading to brand advocacy. This brand-focused study, which goes beyond the technical aspects of AR, is unique and has the potential to inform the strategic decision-making of managers aiming to enhance the customer experience by means of AR implementation.     

Towards Dimensionalizing Warranty Information: The Role of Consumer Costs of Warranty Redemption

Firms routinely offer warranties, often as attempts to differentiate their offerings from those of competitors. Despite this practice common to virtually every consumer durable category, extant research has been inconclusive regarding the effect of warranties on quality judgments. One potential limitation of these prior investigations is the failure to model a key element of a product warranty—consumer‐side transaction costs associated with warranty redemption. In this article, we introduce the role of consumer‐side transaction costs associated with warranty redemption and examine the joint impact of warranty length and warranty redemption costs for brand names of varying strength on consumers’ judgments of product quality. Two experiments show that warranty length signals security but not quality, and that perceived quality increases as consumers’ warranty redemption costs decrease, provided that the warranty length is short. Different dimensions or aspects of warranties have different effects on perceived quality. The implications of the results for understanding conflicting findings in the warranty‐quality literature are discussed.     

The Challenge of Being a Challenger: Social Dominance Orientation Shapes the Impact of “Challenger vs. Leader” Comparisons

The current research investigates when and how comparative advertising effectiveness is shaped by social dominance orientation (SDO), that is, the degree to which one desires to maintain the status quo in social hierarchies. We examine these issues with regard to “challenger vs. leader” comparisons that seek to change the relative standing of competitors in a product category by documenting the superiority of challenger brands over market leaders. Findings demonstrate that the resistance to change characterizing high (vs. low) SDO individuals makes them respond (1) less favorably to “challenger vs. leader” comparisons that seek to alter the existing category hierarchy and (2) more favorably to “leader vs. challenger” comparisons that preserve this status quo in the category hierarchy. The theoretical implications of these findings are discussed, as are avenues for future research.     

Early memories as expressions of relationship paradigms: a preliminary investigation

Earliest childhood memories (EMs) have been utilized as expressions of relationship paradigms, but few empirical studies have been conducted. This study outlines the construction and development of an EM relationship scoring system and scale utilizing nonclinical and clinical samples. It was hypothesized that relationship episodes could be reliably coded using EMs and that they would demonstrate convergent validity with measures of attachment style (Separation-Individuation Test of Adolescence), mood (Profile of Mood States), and clinical symptomatology (Symptom Checklist 90-revised [SCL-90-R] and the Minnesota Multiphasic Personality Inventory [MMPI]). The hypotheses received broad support. Findings indicate that relationship episodes may be reliably coded from EMs. Associations between individual EM variables, the EM relationship scale, and objective measures suggest that the quality of relationships expressed in EMs is associated with degree of general maladjustment. Suggestions for further research are discussed.     

Cultural variations in achievement motivation despite equivalent motivational strength: Motivational concerns among Indian and American corporate professionals

We explored the possibility that persons from two cultures, Indian and American, might be similar in overall levels of motivational strength yet differ significantly in their experience and expression of achievement motivation. We anticipated that Indian, more than American, corporate professionals would incorporate not only self-based but also other-oriented concerns (e.g., for the welfare of co-workers and community members) into their experience of achievement motivation in the workplace. American and Indian corporate professionals responded to an online survey that included a novel measure tapping interpersonal concerns in achievement motivation. Despite the groups being equivalent on multiple demographic indicators and on traditional indices of both motivational strength and motivational orientation, Americans and Indians differed substantially in motivational concerns, with Indians grounding their sense of achievement motivation more strongly in concerns for extended family, co-workers and community. Implications for the study of cultural variations in personality processes are discussed.
