Stereotype Content Model02:16

Stereotype Content Model

14.8K
The Stereotype Content Model (SCM) was first proposed by Susan Fiske and her colleagues (Fiske, Cuddy, Glick & Xu, 2002; see also Fiske, 2012 and Fiske, 2017). The SCM specifies that when someone encounters a new group, they will stereotype them based on two metrics: warmth—or that group’s perceived intent, and how likely they are to provide help or inflict harm—and competence—or their ability to carry out that objective. Depending on the warmth-competence...

Lazarus's Cognitive Appraisal Theory01:20

Lazarus's Cognitive Appraisal Theory

278
Cognitive psychologist Richard Lazarus proposed the cognitive-mediational theory of emotions, which emphasizes how individuals' assessments of stressors significantly affect their experience of stress. According to Lazarus, the stress response is determined by a two-step appraisal process: primary appraisal and secondary appraisal. These cognitive appraisals help individuals evaluate the potential impact of a stressor and determine the adequacy of their coping resources.
Primary Appraisal:...

Therapeutic Communication01:30

Therapeutic Communication

4.5K
Communication is a lifelong learning process. Through therapeutic communication, nurses can collect relevant assessment data, provide education and counseling, and interact during nursing interventions. Sending and receiving messages occur through verbal and nonverbal communication techniques and can happen separately or simultaneously.
Verbal communication depends on language or a prescribed way of using words so that people can share information effectively. The critical aspects of verbal...

Masking and Demasking Agents01:19

Masking and Demasking Agents

2.5K
EDTA titrations may necessitate masking and demasking agents to temporarily protect a particular metal ion in a mixture from the EDTA reaction. These agents facilitate the sequential analysis of the metal ions by forming stable complexes with some—but not all—metal ions during certain steps.
There are many masking agents, such as cyanide, fluoride, triethanolamine, thiourea, and 2,3-bis(sulfanyl)propan-1-ol (formerly 2,3-dimercapto-1-propanol), with the masking agent chosen based on...

Confirmation Biases01:31

Confirmation Biases

5.5K
The confirmation bias is the tendency to focus on information that confirms our existing beliefs and ignore information that is inconsistent with our expectations. For example, if you think that your professor is not very nice, you notice all of the instances of rude behavior exhibited by the professor while ignoring the countless pleasant interactions he is involved in on a daily basis. Have you ever fallen prey to the confirmation bias, either as the source or target of such bias?

Reinforcement01:23

Reinforcement

273
Positive and negative reinforcement are key concepts in operant conditioning, a learning process where the consequences of a behavior affect the likelihood of that behavior being repeated.
Positive reinforcement occurs when a behavior is followed by the presentation of a rewarding stimulus, increasing the frequency of that behavior. For example:

Area of Science:

  • Human-Computer Interaction
  • Artificial Intelligence
  • Robotics

Background:

  • Smart speakers are common in homes but not workplaces due to privacy and trust concerns.
  • Abstract conversational agents lack social cues, hindering workplace adoption.
  • Embodiment may enhance trust and social presence for workplace AI.

Purpose of the Study:

  • To investigate the impact of embodiment on trust, engagement, and performance in a workplace setting.
  • To compare a humanoid robot, a smart speaker, and a dialogue manager in a first responder scenario.
  • To assess the role of anthropomorphic features in user perception of AI agents.

Main Methods:

  • Mixed-methods study involving a first responder team.
  • Comparison of a humanoid robot, a smart speaker, and a custom dialogue manager.
  • Evaluation of trust, engagement, cognitive load, and human performance.

Main Results:

  • The humanoid robot, with facial features and eye gaze, was potentially more trusted than the smart speaker.
  • Embodied conversational agents increased task engagement and performance compared to the smart speaker.
  • Subjective trust is complex, but embodiment appears to positively influence user experience.

Conclusions:

  • Embodiment, particularly with anthropomorphic features, may facilitate the integration of conversational agents into professional environments.
  • Further in-situ studies are recommended to validate findings with domain workers.
  • Robotic embodiment shows promise for improving human-AI collaboration in task-oriented settings.
