• Blocking of Stimulus Control and Conditioned Reinforcement 

      Vandbakk, Monica; Olaff, Heidi Skorge; Holth, Per (Psychological Record;, Journal article; Peer reviewed, 2020-03-31)
      Stimuli with no specific biological relevance for the organism can acquire multiple functions through conditioning procedures. Conditioning procedures involving compound stimuli sometimes result in blocking, related to the ...
    • Blocking of Stimulus Control in Children with Autism 

      Olaff, Heidi Skorge; Vandbakk, Monica; Holth, Per (The Psychological Record;Volume 72, issue 2, Peer reviewed; Journal article, 2021)
      The present study aimed to investigate the blocking of stimulus control in three children with autism. We used a go/no-go procedure in a standard blocking paradigm. In Phase 1, we established one of two sounds or colored ...
    • Conditioned Reinforcement: the Effectiveness of Stimulus—Stimulus Pairing and Operant Discrimination Procedures 

      Vandbakk, Monica; Olaff, Heidi Skorge; Holth, Per (The Psychological Record;, Journal article; Peer reviewed, 2018-09-12)
      The purpose of the present experiment was to evaluate which method, stimulus – stimulus pairing or operant discrimination training, establishes neutral stimuli as more effective conditioned reinforcers, and to explore ...
    • Effects of meaningful stimuli contained in different numbers of classes on equivalence class formation 

      Mensah, Justice; Arntzen, Erik (Journal article; Peer reviewed, 2016)
      Previous experiments have investigated the function of using pictures or meaningful stimuli on equiv- alence class formation. For example, when attempting to form three 5-member classes (A → B → C → D → E), ...
    • Social categorization and stimulus equivalence: A systematic replication 

      Strand, Rebekka; Arntzen, Erik (The Psychological Record;70, Journal article; Peer reviewed, 2020-01-02)
      A systematic replication of Watt, Keenan, Barnes, and Cairns (1991) was conducted on two groups of Norwegian soccer supporters. The 24 participants were trained conditional discriminations for the emergence of three 3-member ...
    • Tailoring of painful stimuli used for exploring transfer of function 

      Eilertsen, Jon Magnus; Arntzen, Erik (The Psychological Record;70, Journal article; Peer reviewed, 2020-03-04)
      Fifteen college students rated the degree of painfulness of six images showing needle injections to different parts of a human hand. The images were rated on a scale ranging from 1 (not painful) to 5 (severely painful). ...
    • Yield as an essential measure of equivalence class formation, other measures, and new determinants 

      Fields, Lanny; Arntzen, Erik; Doran, Erica (The Psychological Record;70, Journal article; Peer reviewed, 2020-03-31)
      “Yield,” the percentage of participants in a group who form a set of equivalence classes, has been used very broadly to identify the effect of different training protocols on class formation and expansion, identify variables ...
